build R source package in place from CVS?
I'm currently using R CMD INSTALL to build and install some of my own custom R packages. Basically, I use a script which first builds a tarball of my R source code, and then calls R CMD INSTALL, which builds and installs that source package from the tarball, including re-compiling all my C code from scratch every single time, which is both totally unneccessary and tediously slow. What I would like to do instead (and what I do in fact do with S-Plus) is simply cd to the directoy where the production copy of my R package lives, do a CVS update, and then rebuild my R package right there in that directory. I do not want to generate any intermediary tarballs nor copy the package files to any other locations. Is there any current way to build R packages in place like that? Or if not, how would you suggest I go about accomplishing this? Thanks!
