Why do I see this error?
Because there _is_ no applicable method. Please don't name objects after R functions, but in your case you need to do class(aov) ?TukeyHSD ?aov and see what TukeyHSD says it handles and what aov says it returns. This question has been answered at length on this list quite recently, so please also search the archives.
library(stats) require(stats)
[1] TRUE
tHSD <- TukeyHSD(aov)
Error in TukeyHSD(aov) : no applicable method for "TukeyHSD" In case it helps:
