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.
Thanks,
Clayton
