[R] install.packages() for local source file

[Paul Roebuck]

Wish to install a local source package on Un*x platform from
within R. Same thing as I can accomplish from cmdline as

$ export R_LIBS=~/R/library
$ cd /path/to/pkg
$ R CMD INSTALL -l $R_LIBS <pkgname>


So, how do you go about this anyway?
And isn't this a bug in 'install.packages'?
