Suppose I have an R package installed on my system, but the source code (tarball etc.) is hard to retrieve. I'd like to find the easiest way to reconstruct as much of the package as possible (R code, man pages, etc.; in this case there are no binaries/compiled code in the package), i.e. I'd like to reverse-engineer the source code of the package.
The installed version of an R package on my system has the following directories:
data DESCRIPTION help html INDEX libs LICENSE Meta NAMESPACE R
For a package called foo, the R and help directories (which are of greatest interest) each contain files foo.rdb, foo.rdx; these are not particularly human-readable (see here, here).
Top priority is recovering the R code in source form; it would be nice to fully reverse-engineer and get man directory as well ...
