Hi everyone,
I run the R loops on window XP and vista. Both are Intel core 2 Duo
2.2 GHz with 2 GB ram and XP is significantly faster than vista. Dose
anyone know how speed up R loops in vista?
Thank you in advance.

Didn't someone post not too long ago that apply is
internally represented as a for-loop? Or am I not
remembering this correctly?

Well .. I'm waiting for the experts to jump in and give us the
straight story on this :-)
All of the algorithms are represented internally
