[R] multiple comparison (glht) problem

[Anqi Qiu]

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!
