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.
