Re: [R] Get home directory and simple I/O
From: Gabor Grothendieck
See:
?R.home
That's not what Alberto wanted: It gives the location of the R
installation, not where user's home directory is. AFAIK Windows does
not set the HOME environment variable by default.

Re: [R] Get home directory and simple I/O
But the request was for a *generic* solution. On Windows there might not be anything corresponding to a home directory (and the rw-FAQ discusses the concept and how R resolves this).
