Dear all,
My apologies if this has been discussed before. When estimating a model
with lmer, I can't see anymore the contents of the "name" column in the
Random effects part of the output. See the example below

How can I know which variance correspond to the subject random
intercept and which one to the subject slope Days? As far as I remember
this information was available in previous versions. Is this a bug?
Thank you very much in advance
Jorge
