Dear R  

Christoph Lehmann asked about this recently- as seen at http://finzi.psych.upenn.edu/R/Rhelp02a/archive/53191.html but the reply was not detailed. Did Christoph get a solution to this?  

Can anyone point me toward how to do repeated measures comparison using the the friedman test or other non-parametric test? I am trying to do something similar. Any example code would be useful.  

If anyone is willing to help I have example data I can provide. The variables are  

TT(=treatment), date, cover

7 treatments (only 5 replicates each), 6 measurements 2 months apart, %cover of treated plants  

Cheers
