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.

Subject: 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".
