the just released version 0.5.7 supports a new method to enhance RKWard with 
external plugins, as well as a new way of generating those plugins. i took the 
liberty of writing one for ANOVAs. it's not perfect, but can easily be 
improved. if you'd like to have look, here's how you get it:

 - make sure you have RKWard >= 0.5.7 installed
 - "settings" -> "configure packages" -> "install/update/remove" tab
   -> look for the package "rk.ANOVA" amongst "new packages"

this package is the ANOVA plugin (that is, external RKWard plugins are now 
simple R packages). once you've installed it, you should find three additional 
dialogs in the menus:
 - "analysis" -> "ANOVA"
 - "analysis" -> "means" -> "t-tests" -> "pairwise t-tests"
 - "plots" -> "interaction plot"
   ("generic plot options" don't work yet)

note however, that the plugin depends on ezANOVA() (package "ez") for the 
ANOVAs, which might take some time to install as it has in turn some 
dependencies (and currently also a bug causing it to fail for pure between 

for those interested, the plugin sources also include the R script that 
created the whole plugin (using the new rkwarddev package).

comments and suggestions welcome!
