 Hi,

 I use glht to make multcomp, using Tukey, from a glm model.

 It is possible to get a more simplified output of result? Somethink like
 ordering by letters.

 Thanks
 Ronaldo

I try to use multcompLetters, but dont work

Look

 mc- glht(m.pesofruto,linfct=mcp(Ind=Tukey))
 
 summary(mc)

 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   -0.112130.08760  -1.280  0.9724
3 - 1 == 0   -0.693900.08715  -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

I don't yet understand what you are looking for.

Can you post a reproducible example, preferably an example from ?glht,
of what you are getting and of what you want.

Rich
