I am very new to R. I have some data from a CVS stored in vdata with 4 columns labeled: X08, Y08, X09, Y09. I have created two new "columns" like so: Z08 <- (vdata$X08-vdata$Y08) Z09 <- (vdata$X09-vdata$Y09) I would like to use chisq.test for each "row" and output the p-value for each in a stored variable. I don't know how to do it. Can you help? so far I have

Hello, I have found what I believe to be a bug in the Linux version of the Rscript binary. Under Windows (official 64-bit 3.5.1 R distribution running on an up-to-date Win10), I can do the following (e.g. under powershell): PS H:\Users\Cesko> Rscript -e 'ls() >> ls()' character(0) character(0) which works as I expect: I am running Rscript with two arguments, namely (1)

The loop that echoes the arguments almost always stops too soon. It apparently does that to avoid echoing the "--args" (that had been inserted) when there are no user arguments. However, when there are user arguments, the next element of the 'av' array is the last argument and usually not "--args", although it can be. ?Rscript is a little sketchy: ?--verbose?

Hi, I have a bunch of R scripts which have the hash bang !/usr/bin/env Rscript and I typically run these scripts by passing in some parameters like this: ./nameOfRScript arg1 arg2 ... I know Rscript has the option to run in --vanilla. Where exactly do I insert the --vanilla option? When I do something like this: ./nameOfRScript --vanilla arg1 arg2 ... And I try to access the commandArgs,

Dear R experts This probably seems very easy to you guys, but I'm a beginner and would be really glad if someone helped me with this: I am trying to automate the execution of an R script (let's call it "myscript.R") by passing a variable from a bash script to myscript.R. I know I can use the command Rscript, but I don't know how to declare in bash which variable will be

Hello list Is there a way of identifying from within R whether a script has been source(d) from Rgui.exe or via Rscript.exe in batch mode? For the code I have I use the commandArgs() function to pick up command line args when running in batch mode via Rscript.exe However I like to get the code working manually first using source("MyRCode.r") I'd like to be able to put something at

Hola. Tengo un script con la siguiente estructura. #!/usr/bin/env Rscript args = commandArgs(trailingOnly=TRUE) source("carga-datos.R") source("modelo.R") y quiero llamar a mi script desde consola con Rscript --vanilla miscript.R datos1.csv De forma que se guarde como argumento el nombre del fichero que quiero cargar y se pase a al script carga-datos.R. El problema es

I think there's a minor bug in the argument-processing carried out by Rscript. The effect is that if one passes "-g" as a flag to the script, it is erroneously exposed to the main executable's argument processing and therefore generates a message about not being able to comply with the request for a particular GUI. Uppercase G is fine as are the other 25 letters in upper or

Dear R experts: I am a bit stymied by how the argument picking-off works in R batch file usage. $ cat commandArgs.R cat(" Command Line Arguments were ", commandArgs(), "\n"); $ /usr/bin/R CMD BATCH commandArgs.R --args 1 2 3 $ /usr/bin/R --args 1 CMD BATCH commandArgs.R ... I am now getting into interactive mode ?! I guess it really is skipping the rest of the command line

I have the following script (also attached): #!/usr/bin/Rscript spec=matrix(c( 'verbose', 'v', 1, "integer", 'help' , 'h', 0, "logical" ),ncol=4, byrow=TRUE) spec.dim=dim(spec) spec.opt.long=spec[,1] spec.opt.short=spec[,2] spec.opt.l <- spec.dim[1] infile <- "test.dat" args=commandArgs(TRUE); l=length(args) self =

I would like to write a block of code that runs when a script is being run from Rscript, but not to run if the same file is being source()d, or submitted via ESS, etc. As a gloss I would like to write a file that looks somewhat like: #!/usr/bin/env Rscript my.func <- function(...) { #do something... } if ( #is.running.Rscript# ) { do.call(my.func, commandArgs(trailingOnly=TRUE)) }

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.

Dear R People: I have used ./R --no-save -q -f e.in >stuff.out with great success on SUSE10.1 with R-2.7.1. My question is, please: is there a way to pass in a variable to the e.in file? I'm fairly sure that the answer is no, but thought I'd double check. Thanks in advance, Sincerely, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences

Greetings All, I am looking to write a parametrized Rscript that will accept a variable name(that also is the name of the flat file), transform the data into a data frame and preform various modeling on the structure and save the output and plot of the model. In this example i am using a rpart decision tree. The only problem i am having is integrating the parameter into the internal object name

Hi, $ cat commandArgs.R args=commandArgs(trailingOnly=TRUE) args[1]+10 I have the above code. But the following command line gives me an error. I am wondering what is the correct way to convert a string to a vector? $ Rscript commandArgs.R 1:3 > args=commandArgs(trailingOnly=TRUE) > args[1]+10 Error in args[1] + 10 : non-numeric argument to binary operator Execution halted Regards, Peng

I have examined the documentation for batch mode use of R: R CMD BATCH [options] infile [outfile] The documentation for this seems rather spartan. Running "R CMD BATCH --help" gives me info on only two options: one for getting help and the other to get the version. I see, further on, that there are options for retoring and saving sessions (which I do not need to do in this case),

Hi all, I am setting up some R program files for use by our DB programmers to enable them to utilize some R functions which will be called from within TCL code. R has been installed on an RHEL server and R will process the results of SQL queries against an Oracle database. In some cases, they will generate a data file to be read in and processed by R, in others they will simply make the

Hi there, I am trying to find an example how to use Rscript Let's suppose I want to pass 3 arguments (I don't want [options] and -e [expressions] as described in help) *on the command line myRscript.R -arg1=value1 -arg2=value2 -arg3=value3 *In the script #! /path/to/Rscript args = commandArgs(TRUE); >From what I see args is just a string, do I do things correctly ? -- View this
