[R] OT statistics question on TukeyHSD

[Dylan Beaudette]

Hi,

I have a dataset that is stratified by 3 levels, with an unequal number of 
observations per strata:

A	     B	    	   C
182       182        91

The data are approximately normally distrubuted. 

Is there any reason why I can NOT use TukeyHSD to do pair-wise comparison of 
means?

Any thoughts or references would be greatly appreciated.

Thanks,
Dylan
