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,

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

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.

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

One of the examples in Rscript.Rd seems mis-formatted, in that the format statement is incomplete: ## Not run: Rscript -e 'date()' -e 'format(Sys.time(), " Both Rscript.Rd in R 2.5.0 and the version at: https://svn.r-project.org/R/trunk/src/library/utils/man/Rscript.Rd have Rscript -e 'date()' -e 'format(Sys.time(), "%a %b %d %X %Y")' Do

Wanting a commandline solution (for a problem detailed @ http://mailman.unidata.ucar.edu/mailing_lists/archives/netcdfgroup/2012/msg00279.html ) I turned to Rscript, and whacked out the q'n'd https://github.com/TomRoche/GEIA_to_netCDF/blob/master/netCDF.stats.to.stdout.r However it wasn't as quick as hoped, because I spent quite a bit of time figuring out how to pass the arguments.

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

Current R release (3.5.2) and devel return a 0 exit status on error, while prior versions returned a non-zero exit status. On Linux and MacOs, the following line returns TRUE for R-3.5.2 and R-devel, and FALSE for R-3.5.1 and R-3.5.0: system2("Rscript", c("-e", shQuote("stop('foo')"))) == 0 I didn't find this in the NEWS, so I believe this is a bug.

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

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 =

On UNIX one can use #! notation. It would be nice to be able to do something similar on Windows. This could be done by giving Rscript the capability of skipping over the first few lines. For example, there might be a --skip=n argument or perhaps Rscript would skip over any consecutive leading lines that begin with @ in the R file since that cannot be syntactically correct R but does have

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
