pairwise comparisons among treatments

Hello Bert,

Thanks for your response. I don't know why I am getting following 
error messages. I use version of "R version 2.1.1, 2005-06-20, 
powerpc-apple-darwin7.9.0 " in Mac OS X version 10.3.8.
I did try to load following packages before, but it failed.

help.search("pairwise comparison")
Error in help.search("pairwise comparison") :
	could not find package 'arrayQuality.1'
In addition: Warning messages:
1: no Rd contents for package 'R2HTML' in 
'/Library/Frameworks/R.framework/Resources/library' in: 
help.search("pairwise comparison")
2: no Rd contents for package 'affylmGUI' in 
'/Library/Frameworks/R.framework/Resources/library' in: 
help.search("pairwise comparison")

Thanks.

Kevin
