[R] run a script during R CMD build
I would like R CMD build to run some R code which does some stuff and save the result as a file in /inst/docs folder. Is there any way of doing this. Thank you. Johan We won't tell.

Re: [R] run a script during R CMD build
Yes, one way is to use commandArgs in the R script. So say your R script is as follows n - as.character(commandArgs()[3]) fn - as.character(commandArgs()[4]) mat - matrix( rnorm( n*n ), nc=n ) write.table( mat, filenames=fn, sep=\t, quote=FALSE ) Then you execute the commands from command line as R --no-save script 100 out.txt This will run the R commands and output them to out.txt. johan Faux wrote: I would like R CMD build to run some R code which does some stuff and save the result as a file in /inst/docs folder.

Re: [R] run a script during R CMD build
Thanks for your help. Maybe I was not clear in my question. Let say I have a R script , myscript.R which produce some file mydata.Rdata and saves them in /inst folder. My question is where to I put my script so that it will run when I build the package using R CMD build ? I want to include mydata.RData in my package and I want it to be updated every time i build the package. I appreciate your help anyway. -Johan - Original Message From: Adaikalavan Ramasamy [EMAIL PROTECTED] To: johan Faux [EMAIL PROTECTED] Cc: r-help@stat.math.ethz.ch Sent: Tuesday, March 20, 2007 12:10:21 PM Subject: Re: [R] run a script during R CMD build Yes, one way is to use commandArgs in the R script.

Re: [R] run a script during R CMD build
Sorry, I did not read the question properly. I believe all your functions goes in mypkg/R and your data goes into mypkg/data subdirectory respectively but I am no expert in this area. If you want to reflect your data from one folder to another, you can try using a symbolic or soft link in *nix systems ln -s /inst/mydata.Rdata /somewhere/mypkg/data . Not sure if it the symbolic link approach will work when you try to R CMD BUILD mypkg. You might be interested in the examples in package.skeleton().
