See ?path.package and ?file.path
Example:
> require(WriteXLS)
Loading required package: WriteXLS
# I am on OSX
> path.package("WriteXLS")
[1] "/Library/Frameworks/R.framework/Versions/2.13/Resources/library/WriteXLS"
I have Perl scripts in my package, which are in the /inst/Perl folder in the
package source, so:
> file.path(path.package("WriteXLS"), "Perl/WriteXLS.pl")
[1]
"/Library/Frameworks/R.framework/Versions/2.13/Resources/library/WriteXLS/Perl/WriteXLS.pl"
