# Completion warning in glht

I am running a sequence of post-hoc tests with glht (mutcomp package), but the function summary warns me that the algorithm ends with an error > abseps.

> hr.ph <- glht(hr.lm, linfct = ph_conditional);
> summary(hr.ph)

Warning messages:
In RET\$pfunction("adjusted", ...) : Completion with error > abseps


Does anybody know what that means? I think it is a matter of modifying the parameters of the algorithm that summary runs. Looking at the documentation, I could not find a way of actually doing so. Do you have any suggestion? Also, how does one know the default values of these algorithms?

Thanks a lot!
