Identifying Splus vs. R

[Dennis Fisher <fisher@plessthan.com>]

Colleagues,

I have written code that will be run in either Splus or R, depending on certain circumstances.  Most of the code runs interchangeably with the two programs.  But, in certain instances, I need to modify code so that it is specific for Splus or R.  Ideally, I would like to test which program is running.  If I enter the command:

version$language

R returns "R" whereas my version of Splus (6.0) returns NULL.  I can parse these to obtain the desired result but I was wondering if anyone has a more sophisticated approach to this issue.
