Does R have a command for sending emails?

Hoping this helps! (Of course, if you're not a unixoid, this
is probably no use to you at all, and I have no idea how to
do anything similar in Windows).

How about an R package to talk to google's gmail service, perhaps 
leveraging an existing API, such as:

http://libgmail.sourceforge.net/

  this is written in pure python, so not only is it cross-platform but 
it should be possible to write one in pure R using HTTP calls and the like.

  you could then do statistical analysis of your gmail spam purely in R.

  or am I now getting too silly?
