The only obvious typo is the misspelling of "Tukey". Uppercase is necessary. But that is not the cause of the current error. I can't duplicate the problem from your description. Look at the data.frame data_mcp. If that doesn't give you the hint, then you will need to send the data to the list, the standard "commented, minimal, self-contained, reproducible code."

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. -- Robert A.
