Does anyone know how to extract the convergence code of an lmer object. I
am working in a monte carlo simulation with mixed model and I need to know
if a model has or not convergence. With unclass(mymodel) the following
information attr(,"optinfo")$conv$lme4 can be seen. How can I get this
important information in an automatic way?

Thank's in advance
