... works So it seems the lib.loc path contents in library() and help() gets parsed differently: library() knows about the expansion of "~" to the $HOME variable (because library(tripack,lib.loc="~/R-Lib-x86/") works) but help() does not.
Yes. As "~" is a csh construct, and not in general a valid part of a path, it is just chance that it works for library. index.search(), the tool used by help, does not know about "~". sys.source() as used by library () does. I'll see if I can add "~" to the knowledge of index.search. Generally, though, don't assume that packages know about csh's shortcuts.
