Hi, I wonder if there is any function which gives the number of times which an element is repeated in the matrix. Let say there is a matrix, I would like to find out how many times number 2 has been repeated in the matrix, or in other words, how many elements of the matrix are equal 2. Thanks for your help, Rostam [[alternative HTML version deleted]]

Hi R users, I am trying to create a matrix, but R has problem with the size of dim, wondering if there is anything that I can do? > a <- diag(147456) Error in array(0, c(n, p)) : 'dim' specifies too large an array Thanks for your help Rostam [[alternative HTML version deleted]]

Hi, I have three matrices, Red, Green and Blue. I would like to produce a matrix which is the combined values of Red, Green and Blue matrices. I know rgb() does the job, but the values are not between 0-255, they are in the following format: "#2C312C" I would like to have the values between 0-255. I wonder if you could tell me what I can do... Thanks for your help, Rostam

Hi R users, I would like to create an image using three matrices which contain the values of Red, Green, and Blue of each pixel, i.e. one matrix which has values of red, one which has values of green, and one which has values of blue. The values are between 0 and 1 instead of 0-255. I have obtained the matrices using the getChannels of pixmap library. I wonder if anyone knows how to create the

Hi everyone, I have a matrix containing color values of an image same as following, [1,] "#444444" "#444444" "#434343" "#404040" "#3D3D3D" "#3D3D3D" "#3E3E3E" [2,] "#414141" "#414141" "#414141" "#404040" "#3F3F3F" "#3F3F3F" "#3F3F3F" [3,] "#3E3E3E"

Hi, I know that I can use the following script to get the command line options for an R script. But the output shows two many irrelevant arguments. For example, I only want to pass "a", "b" and "c" to the script. The first 5 elements in the variable 'args' are not what I want. I am wondering what is the correct way to pass command line options to an R script.

It seems, I don't understand something, or there is a bug in R. I have made some experiments after my yesterday post about using "=" with -e switch to the Rscript. Now, I've found: (1) C:\users\wl\trainings\r>rscript --verbose -e "mean(x=1:3)" running 'C:\Program Files\R\bin\Rterm.exe --slave --no-restore -e mean(x=1:3)' Error in -args : invalid

Sorry for not reading carefully and thanks for confirming problem with Rscript too.

Hi all, Is there a function to open a script file from the command line? I have several students who are Mac users and when they open up a script file it does not send commands to the console, and unfortunately I don't know how to solve this problem since I am not a Mac user. I have looked over the FAQ for Mac users, but didn't see a reference to the problem. I think they are both

One comment: For your R devel example you didn't use spaces in the expression, i.e. maybe that's broken too with spaces? Three questions: Does it work if you avoid spaces? Does it work if you use single quotes? Does this also occur for Rscript? Thxs Henrik On Dec 5, 2017 03:44, "G?bor Cs?rdi" <csardi.gabor at gmail.com> wrote: I wonder if this is intended. Thanks,

Dear all I am running in a problem when trying to run R from Windows command line. I am runnning Windows Vista, R-2.10.1. I have a script I would like to run remotely from another program. As it did not work, I thought I would test the script from the Windows command line which highlighted a problem. When I open the command line and type R at the prompt (or any other variant (R CMD BATCH,

Hi, I would like start R in BATCH mode and submit my own parameters. Or in other words, I would like to specify variables from the command line and execute a script using those. I have been looking at commandArgs and calling R from the command line under bash: R CMD BATCH --no-save --args -filename="$filname" -- r-test.R r-test.Rout The problem here is, if $filename contains

Hi - Think this is quick help. Not sure how to trap what is causing my simple script to run fine in R, but fail immediately when called from rscript. I can put all sorts of traps in the script itself, but when called from the command line the r window simply flashes and closes. There's probably a way to find out why rscript is failing, but I don't know it and can't seem to find it

Hi all, Is there any way through which i can run a R file from Command line. For example > r mean.R Thanks and Regards, Vaibhav Gathibandhe [[alternative HTML version deleted]]

Hello, I want to run an r script that contains code for a gui (rgtk) on the command line (windows 2000, 32 bits) using R2.10.1, but the Gui disappears a few miliseconds after I started the program. What switch should I use to prevent this? I tried r.exe, rterm.exe and rscript.exe with various combinations of switches, but none of them works.   TIA Cheers!! Albert-Jan

Dear all, I am having a problem downloading webpages through R when i run it in the DOS window under Windows Vista Basic. I have downloaded the batchfiles from http://code.google.com/p/batchfiles/ and have successfully set the PATH. I open up 'Command Prompt' in Vista and type (after the C:\...> stuff): ### START ### C:\Users\Karen>Rscript -e "library(RCurl);

Hi Guys I am Abhishek, primarily a bioinformatician. I have recently started using a lot of R thanks to some excellent packages available. Lately I have felt the need to batch process few of the R scripts I have been working with and strangely enough I am not able to find a good resource on how to best do this. I did find few old threads on the archives but none convinced me much. So here I am

I don't think it's the path or the slashes. I run other files in this same manner, with the same path to the script itself, and they go off without a hitch. Although this is the first time I am using 3.4.3, and the only script I am using that version of R for at the moment. Having said that, I did TRY reversing the slashes and got the same result. :-) Michael Ashton, CFA Managing
