[R] No "doc" directory in my installation of R.

[Duncan Murdoch]

If you start R just using the regular command line version (not 
RStudio), does

   Sys.getenv("R_DOC_DIR")

point to /usr/share/R/doc ?  The standard R startup script should do 
that, but if it doesn't maybe you've got an override?

Or maybe you have R_DOC_DIR defined yourself?
