Hello

Using R 2.2.1 on a Windows machine.

Has anyone programmed the Welch test for equality of variances?

I tried RSiteSearch, but this gave references to t test and
oneway.test, which are not quite what I need.....I need the Welch test
itself, for use in a meta-analysis (to determine if variances are
equal).


TIA

Peter
