I am not sure whether there is a bug. When I tested the example given for "glht" in the help, I entered the following error:
Running commands: amod <- aov(minutes ~ blanket, data = recovery) rht <- glht(amod, linfct = mcp(blanket = "Dunnett"), alternative = "less") Errors are: Error in try(coef.(model)) : could not find function "coef." Error in modelparm.default(model, ...) : no 'coef' method for 'model' found! Thanks!
