A vector is often written in bold, like a or b so we know it is not a scalar:. R cannot tell which variable is which when you pass it an entire data.frame to plot. B = sortrows(A,column) sorts A based on the columns specified in the vector column.For example, sortrows(A,4) sorts the rows of A in ascending order based on the elements in the fourth column.sortrows(A,[4 6]) first sorts the rows of A based on the elements in the fourth column, then based on the elements in the sixth column to break ties. This should get you headed in the right direction, but be sure to check out the examples pointed out by @Jaap in the comments. This should only take a vector or a matrix. # 1. if annotation_height is set, it needs to be a vector and height is disabled. beside: a logical value. \begin{cases} x1 &= .5x4\\ x2 &= x4\\ x3 &= .5x4\\ x4 & \text{is free}\\ \end{cases} Here is the matrix I pulling the information from just in case you need it. A matrix having only one row is called a row vector. Thus (6,2,−1)+(4,0) is not deﬁned, and (4,0,−1) = (4,0) makes no sense at all. Essentially, the matrix is represented by a Cartesian coordinate system, in which the rows of the matrix are parallel to the x-axis and the columns to the y-axis of … You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. You can alternatively look at the 'Large memory and out-of-memory data' section of the High Perfomance Computing task view in R. Packages designed for out-of-memory processes such as ff may help you. It's generally not a good idea to try to add rows one-at-a-time to a data.frame. Given a list of English words you can do this pretty simply by looking up every possible split of the word in the list. Fixed my typo in the first matrix. I think this code should produce the plot you want. The location of each cell is defined by the row or column where it is located within the raster matrix. Your sapply call is applying fun across all values of x, when you really want it to be applying across all values of i. Note there are arguments like width, height, annotation_width and annotation_height, but they are used to adjust the width/height for the complete heamtap annotations (which are always mix of several annotations). A vector is a series of numbers, like a matrix with one column but multiple rows, that can often be represented spatially. library(reshape2) #ggplot needs a dataframe data <- as.data.frame(data) #id variable for position in matrix data$id <- 1:nrow(data) #reshape to long format plot_data <- melt(data,id.var="id") #plot ggplot(plot_data, aes(x=id,y=value,group=variable,colour=variable)) + geom_point()+ geom_line(aes(lty=variable))... Do not use the dates in your plot, use a numeric sequence as x axis. And if the height is a Matrix of values and beside is FALSE, each matrix column represents the bar, and the row values create stacked sub bars. I think you want to minimize the square of a-fptotal ... ff <- function(x) myfun(x)^2 > optimize(ff,lower=0,upper=30000) $minimum [1] 28356.39 $objective [1] 1.323489e-23 Or find the root (i.e. Try.. zz <- lapply(z,copy) zz[[1]][ , newColumn := 1 ] Using your original code, you will see that applying copy() to the list does not make a copy of the original data.table. I am getting the error "Height must be a vector of Matrix." Speed is how fast something moves. For a barplot, using ?barplot will tell you what is needed: barplot(height, width = 1, space = … If FALSE, the columns of height are portrayed as stacked bars, and if TRUE … You can do this with something like: get_scalar <- function(name, FUN=max) { sapply(mydata[,name], function(x) if(all(x == -999)) NA else FUN(as.numeric(x[x != -999]))) } Note that I've changed your function... r,function,optimization,mathematical-optimization. The norm of a vector is its length, and the length of a vector must always be positive (or zero). If height is a matrix and beside is FALSE then each bar of the plot corresponds to a column of height, with the values in the column giving the heights of stacked ``sub-bars'' making up the bar. It is possible to add both scalar and vector attributes to datasets. If it is a Vector, the R bar chart created with a sequence of rectangular bars, and each bar height depends upon the vector value. The data elements must be of the same basic type. This is only useful when height is a matrix. install.packages('rJava') library(rJava) .jinit() jObj=.jnew("JClass") result=.jcall(jObj,"[D","method1") Here, JClass is a Java class that should be in your ClassPath environment variable, method1 is a static method of JClass that returns double[], [D is a JNI notation for a double array. Scalar and Vector Attributes. For some reason the top and bottom margins need to be negative to line up perfectly. that of a building. Notation. The following are 30 code examples for showing how to use cv2.getRotationMatrix2D().These examples are extracted from open source projects. Using data.table library(data.table) setDT(df1)[, list(pages=paste(page, collapse="_")), list(user_id, date=as.Date(date, '%m/%d/%Y'))] Or using dplyr library(dplyr) df1 %>% group_by(user_id, date=as.Date(date, '%m/%d/%Y')) %>% summarise(pages=paste(page, collapse='_')) ... copy() is for copying data.table's. When v is a vector, each element specifies the fill value in the corresponding column of A.If A is a table or timetable, then v can also be a cell array.. I think the issue might be that you are trying to pass a DataFrame as the height parameter. ; Saying Ariel the Dog runs at 9 km/h (kilometers per hour) is a speed.. I simply want the graph to compare the numbers in a bar stacked side by side.I have not been able to achieve that. The following is an example of a matrix with 2 rows and 3 columns. The height of the simple annotation is controlled by simple_anno_size argument. R — frequencies within a variable for repeating values, how to call Java method which returns any List from R Language? In your case, you have a data.frame with heights in the second column, and names in the first, so you want to do: You can do something like this: print_test<-function(x) { Sys.sleep(x) cat("hello world") } print_test(15) If you want to execute it for a certain amount of iterations use to incorporate a 'for loop' in your function with the number of iterations.... You can create a similar plot in ggplot, but you will need to do some reshaping of the data first. A matrix is a two-dimensional array that has a fixed number of rows and columns and contains a number at the intersection of each row and column. Also, thanks to akrun for the test data. If height is a vector, the plot consists of a sequence of rectangular bars with heights given by the values in the vector. R cannot tell which variable is which when you pass it an entire data.frame to plot. I'll leave that to you. 'height' must be a vector or a matrix 33333 2010-09-13-19:25:50.206 Google Chrome-#135 NA [ reached getOption("max.print") -- omitted 342611 rows ]] It is important to note that y and z must have the same dimensions for vector addition and vector comparisons. Pastebin is a website where you can store text online for a set period of time. A matrix is usually delimited by square brackets. You can use the dates as labels. Matrix. If all # annotation_height are absolute units, height is ignored # 2. if annotation height contains non-absolute units, height also need to be set and the # non-absolute unit should be set in a simple form such as 1:10 or unit(1, "null") Your intuition is correct. Turned out much more complex and cryptic than I'd been hoping, but I'm pretty sure it works. Given your criteria -- that 322 is represented as 3 and 2045 is 20 -- how about dividing by 100 and then rounding towards 0 with trunc(). Assuming that you want to get the rowSums of columns that have 'Windows' as column names, we subset the dataset ("sep1") using grep. In this case, the error, 'height' must be a vector or a matrix is telling you you didn't give the plot function what it wanted. Count number of rows meeting criteria in another table - R PRogramming, Twitter: Get followers from multiple users at once, Store every value in a sequence except some values, Highlighting specific ranges on a Graph in R, ggplot2 & facet_wrap - eliminate vertical distance between facets, how to get values from selectInput with shiny, Limit the color variation in R using scale_color_grey, Appending a data frame with for if and else statements or how do put print in dataframe, Replace -inf, NaN and NA values with zero in a dataset in R, Subtract time in r, forcing unit of results to minutes [duplicate], How to set x-axis with decreasing power values in equal sizes. Dear all, I have a matrix M (lot of lines, 7 columns) and a vector v (again lot of lines but not the same ad M and 3 columns) and I need to find the lines of M for which the first 3 columns are equal to the column of a certain line of v. Instead, the dot operator must be used to get the desired data into a matrix. Either k or h must be non-NULL, if both are non-NULL then k is used and h is ignored. It looks like you're trying to grab summary functions from each entry in a list, ignoring the elements set to -999. I would create a list of all your matrices using mget and ls (and some regex expression according to the names of your matrices) and then modify them all at once using lapply and colnames<- and rownames<- replacement functions. height: either a vector or matrix of values describing the bars which make up the plot. The problem is that you pass the condition as a string and not as a real condition, so R can't evaluate it when you want it to. It's easier to think of it in terms of the two exposures that aren't used, rather than the five that are. So, in some sense what we say is that these 2 vectors(v1 and v2) characterize the space or they form a basis for space and any vector in this space, can simply be written as a linear combination of these 2 vectors.Now you can notice, the linear combinations are actually the numbers themselves. From Hadley's Advanced R, "x$y is equivalent to x[["y", exact = FALSE]]." collapse is the Stata equivalent of R's aggregate function, which produces a new dataset from an input dataset by applying an aggregating function (or multiple aggregating functions, one per variable) to every variable in a dataset. In this case, the error, 'height' must be a vector or a matrix is telling you you didn't give the plot function what it wanted. A feature is a numerical or symbolic property of an aspect of an object. To get the sapply to do what I assume you want to do, you can do the following: sapply(X = 1:length(x), FUN = fun, x =... You can put your records into a data.frame and then split by the cateogies and then run the correlation for each of the categories. If A is a row or column vector, C is the scalar-valued variance.. For two-vector or two-matrix input, C is the 2-by-2 covariance matrix between the two random variables. The variances are along the diagonal of C. Download 9,500+ Royalty Free Height Vector Images. You can try something like this: 郑重声明：本站内容来源于网络，为尊重原创，本站尽力寻找并添加资料原文链接。如有侵权，请及时联系邮箱给我发信删除！, R: Barplot height must be a vector or matrix, How do I filter array of dictionaries by dictionary key, grep with regular expressions won't see files, Tracking events (via google analytics) for hashtag routes in Backbone single page app, strings command in command line tool is not doing anything, libgdx gradle - forgot to make android project, special characters in layout xml of Android project. Groups are defined by the structure of the tree above the cut. Barplot coming back with 'height must be a vector or matrix' Aliyah Bartoletti posted on 15-11-2020 r I've put in my x and y variables as Since the oth_let1 vector has only two members, you get NA.... Use [[ or [ if you want to subset by string names, not $. Lia = ismember(A,B,'rows') treats each row of A and each row of B as single entities and returns a column vector containing logical 1 (true) where the rows of A are also rows of B.Elsewhere, the array contains logical 0 (false).. This should only take a vector or a matrix. Otherwise... You can try cSplit library(splitstackshape) setnames(cSplit(mergedDf, 'PROD_CODE', ','), paste0('X',1:4))[] # X1 X2 X3 X4 #1: PRD0900033 PRD0900135 PRD0900220 PRD0900709 #2: PRD0900097 PRD0900550 NA NA #3: PRD0900121 NA NA NA #4: PRD0900353 NA NA NA #5: PRD0900547 PRD0900614 NA NA Or using the devel version of data.table i.e. You can try something like this: barplot(as.matrix(data), beside=T , legend.text=T, col=c("red" , "green", "blue"), ylim=c(0,140), ylab="height") Hopefully this helps you out. how to read a string as a complex number? v1 <- c('ard','b','','','','rr','','fr','','','','','gh','d'); ind <-... As per ?zoo: Subscripting by a zoo object whose data contains logical values is undefined. [on hold], How to plot data points at particular location in a map in R, How to build a 'for' loop with input$i in R Shiny. Here is some sample code based on what you had in your original problem which will aggregate Twitter results for a set of users: # create a data frame with 4 columns and no rows initially df_result <- data.frame(t(rep(NA, 4))) names(df_result) <- c('id', 'name', 's_name', 'fol_count') df_result <- df_result[0:0,] #... if (length(z) %% 2) { z[-c(1, ceiling(length(z)/2), length(z))] } else z[-c(1, c(1,0) + floor(length(z)/2), length(z))] ... Or you could place a rectangle on the region of interest: rect(xleft=1994,xright = 1998,ybottom=range(CVD$cvd)[1],ytop=range(CVD$cvd)[2], density=10, col = "blue") ... Change the panel.margin argument to panel.margin = unit(c(-0.5,0-0.5,0), "lines"). If you only have 4 GBs of RAM you cannot put 5 GBs of data 'into R'. Velocity is speed with a direction. library("scales") library(ggplot2) reverselog_trans <- function(base = exp(1)) { trans <- function(x) -log(x, base) inv <- function(x) base^(-x) trans_new(paste0("reverselog-", format(base)), trans, inv, log_breaks(base = base), domain = c(1e-100, Inf)) }... R prefers to use i rather than j. Aslo note that complex is different than as.complex and the latter is used for conversion. Putting feature vectors for objects together can make up a feature space.. The 'rows' option does not support cell arrays, unless one of the inputs is either a categorical array or a datetime array. Using IRanges, you should use findOverlaps or mergeByOverlaps instead of countOverlaps. Pastebin.com is the number one paste tool since 2002. it's better to generate all the column data at once and then throw it into a data.frame. You can do myStr <- "0.76+0.41j" myStr_complex <- as.complex(sub("j","i",myStr)) Im(myStr_complex) # [1] 0.41 ... You can try library(data.table)#v1.9.4+ setDT(yourdf)[, .N, by = A] ... You can do it with rJava package. However, if an object travelled a certain height, such as a tossed baseball, then it would be considered a vector. In your case, you're getting the values 2 and 4 and then trying to index your vector again using its own values. However, without your exact dataset, I had to generate simulated data. Thanks a lot! Since all single annotations have same height, the value of simple_anno_size is a single unit value. The angles must be a column vector (i.e., numpy array). For single matrix input, C has size [size(A,2) size(A,2)] based on the number of random variables (columns) represented by A.The variances of the columns are along the diagonal. A.2 MATRICES We can now extend these ideas to any rectangular array of numbers, which we call a matrix… library(ggmap) map <- get_map(location = "Mumbai", zoom = 12) df <- data.frame(location = c("Airoli", "Andheri East", "Andheri West", "Arya Nagar", "Asalfa", "Bandra East", "Bandra West"), values... sapply iterates through the supplied vector or list and supplies each member in turn to the function. Sleep Shiny WebApp to let it refresh… Any alternative? Height is a scalar when defining a constant value, i.e. The operation can then be applied to the matrix. Scalar sz = size(A) returns a row vector whose elements are the lengths of the corresponding dimensions of A.For example, if A is a 3-by-4 matrix, then size(A) returns the vector [3 4].. multivariate multiple regression can be done by lm(). n=length(y) model_a1 <- auto.arima(y) plot(x=1:n,y,xaxt="n",xlab="") axis(1,at=seq(1,n,length.out=20),labels=index(y)[seq(1,n,length.out=20)], las=2,cex.axis=.5) lines(fitted(model_a1), col = 2) The result depending on your data will be something similar: ... You are just saving a map into variable and not displaying it. The first dimension of a variable-size row vector must have fixed length 1. But saying he runs 9 km/h Westwards is a velocity.. See Speed and Velocity to learn more.. Here's a solution for extracting the article lines only. Please suggest! Try something like this: y=GED$Mfg.Shipments.Total..USA. A matrix is a collection of data elements arranged in a two-dimensional rectangular layout. so c is a vector, it has magnitude and direction It, by default, doesn't return no matches though. If height is a vector, the plot consists of a sequence of rectangular bars with heights given by the values in the vector. radians indicates whether or not input angles are given in radians (True) or degrees (False; the default). This array must have the same number of rows as angles. a vector of text used to construct a legend for the plot, or a logical indicating whether a legend should be included. You are using it to copy a list. the height at which to cut tree to produce the groups. We reproduce a memory representation of the matrix in R with the matrix function. height: You can specify either a Vector or a Matrix of values. If you read on the R help page for as.Date by typing ?as.Date you will see there is a default format assumed if you do not specify. Combining the example by @Robert and code from the answer featured here: How to get a reversed, log10 scale in ggplot2? You may choose to create a new dataset to store the result, or you may simply keep the result as a standard matrix. I think the issue might be that you are trying to pass a DataFrame as the height parameter. This is my first general solution and I want to put it in vector form. In linux, you could use awk with fread or it can be piped with read.table. In that case given legend labels should correspond to the rows of height; if legend.text is true, the row names of height will be used as labels if they are non-null. ## Create input input <- `names<-`(lapply(landelist, function(x) sample(0:1, 1)), landelist) filterland <- c() for (landeselect in landelist) if (input[[landeselect]] == TRUE) # use `[[`... some reproducible code would allow me to give you some example code, but in the absence of that... wrap what you currently have in another if(), checking for length = 0 (or just && it, with the NULL check first), and display your favorite placeholder message....
