Hello. I saw that a minor release has been rolled up with binaries coming soon. My question is whether or not the issues identified (I?m thinking mainly of a window focus issue reported on this list) after Sonoma released...

Hello, I'm just wondering what the status of mcmcsamp is in version 0.999375-28 of lme4. No offense intended, but is it working with a lmer() fit? I only ask, because I've read warnings in the past...

When I run summary (from the coda package) on the result of mcmcsamp I get, among other things, some quantiles for the model parameters fit in my lmer() call. Is it correct to interpret say the 2.5% to 97...

Hello. I decided to update my lme4a installation to play with it on my present analysis and noticed an lme4b package at r-forge. Apologies if I missed an announcement, but is lme4 development now in beta stage with lme4b...

I am wondering if there is a way to undo the results of table(). For example if you had a table that looked like the result of table(x, y) or table(x, y, z) is there a simple/elegant...

I don't know if this is what you're referring to, but in ESS the number of octothorpes (#) affects the indentation in the emacs buffer. If I remember right, ### puts it at the beginning of the line, ## the current...
