[rkward-users] [Help] RE: t-Test with Groups?

[SourceForge.net]

The following forum message was posted by tfry at http://sourceforge.net/projects/rkward/forums/forum/165574/topic/5521778:

Hi!

The functionality you are looking for is simply not implemented, in the "official"
RKWard distribution.

However, the RKWard GUI can be extended by plugins. And, in fact, Meik Michalke
has written a plugin that allows to do t-tests on "long" format data. Use
Settings->Manage R Packages, and install package "rk.ANOVA". You will find a
new GUI entry "Pairwise t-Tests". The main point of the plugin is to allow comparing
pairwise differences between 3 or more groups, but it will also work for 2.
Perhaps that is good enough for you, or perhaps you would like to look into
extending our standard t-test dialog yourself:
