I try to use multcompLetters, but dont work
Look

Simultaneous Tests for General Linear Hypotheses
Multiple Comparisons of Means: Tukey Contrasts
Fit: glm(formula = PesoFruto ~ Ind)
Linear Hypotheses:
Estimate Std. Error z value p value
2 - 1 == 0 -0.11213 0.08760 -1.280 0.9724
3 - 1 == 0 -0.69390 0.08715 -7.962 <0.01 ***
...
But using the multcompLetters,
> multcompLetters(mc)
Error in do.call(compare, list(x, threshold)) :
(list) object cannot be coerced to 'double'
What is the error? In manual this say that is to be used with multcomp
objects.
Designed for use with the output of functions like TukeyHSD, dist{stats},
simint, simtest, csimint, csimtest{multcomp}, friedmanmc,
kruskalmc{pgirmess}.
It is not showed the glht function, but in multcomp package this function is a
substitute for simint, simtest, csimint and csimtest.
Any idea?
Thanks
