How to ship R scripts with R packages ?

Hello, (This is a remix of this previous thread: https://stat.ethz.ch/pipermail/r-devel/2009-August/054264.html , but with a concrete example) I am developing some packages that contain scripts (for Rscript) and would like to know what is the best/recommended way to ship these scripts. An example is the "ant" package (R capable version of apache ant, see http://tr.im/xHLs). The package has a ant.R script in the exec directory and here is how I use it : $ `Rscript -e "cat( system.file( 'exec', 'ant.R', package = 'ant' ) ) " ` ... not so pretty. Meanwhile, "Writing R extensions" talks about the exec directory, but it is not clear if I can use it this way or how.
I think exec is a reasonable place to put the script. If you don't want to type that long command above, why not put it in a small function in the package? E.g. define antR <- function() cat( system.file( 'exec', 'ant.R', package = 'ant' ) ) then you can run it with Rscript -e "ant::antR()" Duncan Murdoch
