[R] bug in multcomp?

[Robert Cribbie]

I am running a linear model with achiev as the outcome and major as my 
iv (5 levels). The lm statement runs fine, but for the glht command I 
get the following error. I noted that someone else asked the same 
question a while back but received no reply. I am hoping someone might 
know what is happening.

 anovaf2<-lm(achiev ~ major, data=data_mcp)
 > pairwise<- glht(anovaf2,linfct = mcp(major = "tukey"))
Error in mcp2matrix(model, linfct = linfct) :
        Factor(s) major have been specified in 'linfct' but cannot be 
found in 'model'!


Any help would be much appreciated.

Rob.
