The primary reason is for development. I do install via the traditional R CMD INSTALL (or variant) method, but I want to keep the C code external from the R package. In particular, I want to be able to modify the C code (and thus the compiled .so library functions) without having to constantly re- install the R package, or constantly copy the shared object library to the /libs/ subdirectory in the R package directory.
The crux of the matter is that this seems do-able: it basically works using dyn.load, just not easily with library.dynam, which is what confuses me. The vast majority of other UNIX-ish applications will somewhere allow me to specify a non-standard library location, if needed In many cases, this is done (in an ad-hoc, and thus unstable manner) using LD_LIBRARY_PATH, but this doesn't seem to be working for me in this instance.
