[R-pkg-devel] Is it possible to reverse engineer a package from the installed library directory ?

[Ben Bolker]

  You could take your old install and do this:

   library("your_package")
   funs <- ls(pos="package:your_package")
   dump(funs,"your_package.R")

   that wouldn't recreate documentation, NAMESPACE files, etc., but it 
would be a start.
