[R] run setwd at the launch of R

It may be disgusting, but I'm not how you expect R to know where to startup.

On my Mac, I keep all my scripts in a per-project working directory.

I therefore type

cd ~/Documents/ataxia

If you have multiple nested directories then why not create a
directory alias (soft-link) so it is easy to "cd" to? Or move the
relevant folders to a better place?

Alternatively, use the Mac OS X GUI, which has an option in
preferences about "initial working directory".
