[R] programmatic installation

[A.J. Rossini]

Okay, so I've got a set of directories containing unpacked R packages
(unpacked, since for various sensible reasons, I'm editing them in warped
ways). 

Supposing that these are in:

        /home/rossini/Runpacked

I thought I could do something like:

install.packages("MyUnPackedRPackage",   # top package name
                 lib="/home/rossini/lib/R", # where I'd like to install
                 destdir="/home/faculty/rossini/sandbox/madman/Rpacks") ## assuming
                                        ## this is where it goes.

But this isn't the right incantation.  I know that I could simply
shell out using system, i.e. system("R CMD install /path/to/dir"), 
but is there a cleaner way?

best,
-tony
