I've tried that as well, and I get an error like:

>Error in rep.int(n, length(means)) : unimplemented type 'NULL' in 'rep'

>4: In replications(paste("~", xx), data = mf) :

however, I think its a problem with my data, something about how Rexcel
imported it, becuase when I do it on the example data in the HSAUR package,
it works....

I'll try importing the data manually.
