Use --vanilla

[hadley]

Should R() always use --vanilla to ensure that it doesn't pick user or site profiles?

It would be nice if it still read ~/.Renviron. Maybe --no-save --no-restore --no-site-file --no-init-file, but not --no-environ?

Or at least make it optional somehow.

What's the advantage of reading .Renviron?

[wch]

All my packages are installed in ~/R because of how my .Renviron file is set up.

But that's ok - R() already captures your libpath from your current session.
