This is what I wrote some time ago in an off-list message: "When I published my first (and still only) R package I also found it daunting to get it working. Perhaps the easiest way to get it going---at least it worked for me---would be to: - take the source archive of an existing package with a very-simple-structure (nortest or even Rcmdr) or a package that would be very similar to what you need [consider the potential licence issues, though] - get rid of/replace files as needed - not forget to run R CMD check (to check that the code conforms to CRAN requirements) and R CMD build (to build the release tarball) - then what rests to do is drop the latter on the CRAN FTP server." It's been some time that I did this, so there might be some missing step. Hope this is of help.
