Version 0.1.2 of r (pronounced littler) was just rolled up.
This version adds two new command-line switches:
-tselects per-session temporary directories in the same way as R does (with thanks to Paul Gilbert for the suggestion), and
-qskips autoloading of default libraries at startup for another small yet noticeable gain in startup speed (with thanks to Simon Urbanek).
As usual, our code in our svn archive, on my r page, and in the local directory here. A fresh package is in Debian’s incoming queue, and Jeff’s littler page at Vanderbilt should reflect the new release soon too.
