I can prove I've done this before, but I recently installed Rexcel (and it was easiest to reinstall R and some other bits to make it work) and now its no longer working.
Before I would do an ANOVA and a tukey post-hoc like this: >data1.aov=aov(result~factor1*factor2, data=data1) then... >TukeyHSD(summary(data1.aov)) and it would give me a nice tukey table of all the pairwise comparisons, now though it gives me: >in UseMethod("TukeyHSD") : no applicable method for "TukeyHSD" Has something changed? Does TukeyHSD no longer accept aov results? Is there a package I'm missing? I am very frustrated.
