R help - Oct 2009 - doing a Tukey HSD post-hoc

Hi all

I have a large spreadsheet (Excel) file with many rows and columns in it. I have
four treatment groups and using the lm function shows that there is a
significant omnibus R with respect to several of the variables. I want to do a
Tukey HSD in R. How can I do this?
