multivariate multiple regression can be done by lm(). Combining the example by @Robert and code from the answer featured here: How to get a reversed, log10 scale in ggplot2? This should get you headed in the right direction, but be sure to check out the examples pointed out by @Jaap in the comments. Matrix. A matrix is usually delimited by square brackets. Scalar A feature vector is a vector containing multiple elements about an object. 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. You are using it to copy a list. 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. It's generally not a good idea to try to add rows one-at-a-time to a data.frame. # 1. if annotation_height is set, it needs to be a vector and height is disabled. Thanks a lot! A vector is a series of numbers, like a matrix with one column but multiple rows, that can often be represented spatially. The norm of a vector is its length, and the length of a vector must always be positive (or zero). This array must have the same number of rows as angles. However, without your exact dataset, I had to generate simulated data. that of a building. v1 <- c('ard','b','','','','rr','','fr','','','','','gh','d'); ind <-... As per ?zoo: Subscripting by a zoo object whose data contains logical values is undefined. The angles must be a column vector (i.e., numpy array). We reproduce a memory representation of the matrix in R with the matrix function. 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. The height of the simple annotation is controlled by simple_anno_size argument. The following are 30 code examples for showing how to use cv2.getRotationMatrix2D().These examples are extracted from open source projects. A negative length makes no sense. 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 $objective [1] 1.323489e-23 Or find the root (i.e. The first dimension of a variable-size row vector must have fixed length 1. In this case, the error, 'height' must be a vector or a matrix is telling you you didn't give the plot function what it wanted. Please suggest! library("scales") library(ggplot2) reverselog_trans <- function(base = exp(1)) { trans <- function(x) -log(x, base) inv <- function(x) base^(-x) trans_new(paste0("reverselog-", format(base)), trans, inv, log_breaks(base = base), domain = c(1e-100, Inf)) }... R prefers to use i rather than j. Aslo note that complex is different than as.complex and the latter is used for conversion. R cannot tell which variable is which when you pass it an entire data.frame to plot. A feature is a numerical or symbolic property of an aspect of an object. This should only take a vector or a matrix. Groups are defined by the structure of the tree above the cut. the height at which to cut tree to produce the groups. beside: a logical value. library(reshape2) #ggplot needs a dataframe data <- as.data.frame(data) #id variable for position in matrix data$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. 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. If h is a vector of numbers, the output will be a matrix with a column for each value in h. The default is NULL. 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.. if you still want to pass it as string you need to parse and eval it in the right place for example: cond... Fitted values in R forecast missing date / time component, Convert strings of data to “Data” objects in R [duplicate], Keep the second occurrence in a column in R, Converting column from military time to standard time, Fitting a subset model with just one lag, using R package FitAR, Remove quotes to use result as dataset name, R: recursive function to give groups of consecutive numbers, How to split a text into two meaningful words in R. How (in a vectorized manner) to retrieve single value quantities from dataframe cells containing numeric arrays? 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. For a barplot, using ?barplot will tell you what is needed: barplot(height, width = 1, space = … hist(x) creates a histogram bar chart of the elements in vector x.The elements in x are sorted into 10 equally spaced bins along the x-axis between the minimum and maximum values of x. hist displays bins as rectangles, such that the height of each rectangle indicates the number of elements in the bin.. Turned out much more complex and cryptic than I'd been hoping, but I'm pretty sure it works. Try something like this: y=GED$Mfg.Shipments.Total..USA. Pastebin.com is the number one paste tool since 2002. height: either a vector or matrix of values describing the bars which make up the plot. This is my first general solution and I want to put it in vector form. The following is an example of a matrix with 2 rows and 3 columns. Sleep Shiny WebApp to let it refresh… Any alternative? Here is some sample code based on what you had in your original problem which will aggregate Twitter results for a set of users: # create a data frame with 4 columns and no rows initially df_result <- data.frame(t(rep(NA, 4))) names(df_result) <- c('id', 'name', 's_name', 'fol_count') df_result <- df_result[0:0,] #... if (length(z) %% 2) { z[-c(1, ceiling(length(z)/2), length(z))] } else z[-c(1, c(1,0) + floor(length(z)/2), length(z))] ... Or you could place a rectangle on the region of interest: rect(xleft=1994,xright = 1998,ybottom=range(CVD$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"). 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. Since all single annotations have same height, the value of simple_anno_size is a single unit value. 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. 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. height: You can specify either a Vector or a Matrix of values. 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. The operation can then be applied to the matrix. 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. A vector is often written in bold, like a or b so we know it is not a scalar:. Your sapply call is applying fun across all values of x, when you really want it to be applying across all values of i. It, by default, doesn't return no matches though. I simply want the graph to compare the numbers in a bar stacked side by side.I have not been able to achieve that. If height is a vector, the plot consists of a sequence of rectangular bars with heights given by the values in the vector. I think this code should produce the plot you want. 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 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. It is possible to add both scalar and vector attributes to datasets. R — frequencies within a variable for repeating values, how to call Java method which returns any List from R Language? I am getting the error "Height must be a vector of Matrix."

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. 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. Either k or h must be non-NULL, if both are non-NULL then k is used and h is ignored. a vector of text used to construct a legend for the plot, or a logical indicating whether a legend should be included. However, if an object travelled a certain height, such as a tossed baseball, then it would be considered a vector. You can use the dates as labels. 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. 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 … Since the oth_let1 vector has only two members, you get NA....

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. This should only take a vector or a matrix. If A is a table or timetable, then size(A) returns a two-element row vector consisting of the … 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. It's easier to think of it in terms of the two exposures that aren't used, rather than the five that are. Assuming that you want to get the rowSums of columns that have 'Windows' as column names, we subset the dataset ("sep1") using grep. I'll leave that to you. I think the issue might be that you are trying to pass a DataFrame as the height parameter. 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(). If FALSE, the columns of height are portrayed as stacked bars, and if TRUE … Here's a solution for extracting the article lines only.
