R help - Sep 2012 - for help post-hoc comparisons

Dear R community 
    In my experiment, there are three treatments (F, R, and S), and the  storge
temperatures of these seeds were 4, 10 and 15. The seeds number of the treatment
were the same. The question is whether the treatments and storage temperatures
changed the seed germinating. The data attached as a ".csv" file names
"g.csv".  I performed a generalized linear mixed model using glm. 
Time and Temp are significant (p < 0.0001) and I would like to perform
post-hoc  comparisons  to check  where the difference among  Time and temp
categories but I did not find  a solution  in R help list or others.

Thank you very much in advance for your help.

The mail server checks to see what file type is attached. If it is not  
mime-text, it gets discarded, and I suspect that your mail client sent  
it as something else. You might get better success with a vanilla  
editor like Notepad on Windows or TextEdit.app on a Mac and make sure  
to save with extension ".txt".

If you want everyone to "be on the same page" you should also include
your code.

You might want to look at ?p.adjust to see if it will meet your post- 
hoc testing needs. If not you can also look at the multcomp package.
