Doug and list

No, the change as reported on my XP PC was Matrix package 0.995-1 was found but lme4 requires >= 0.995.2.

The format change was from a dash to a dot.

Maybe a few more would spell SOS!

But it's the sort of thing where sometimes even the geniuses very close to the work may read the string they think they wrote by gestalt. As long as it is what was intended and works, it doesn't matter.

But what about working in logits. Each new mini-version would have a constant amount of logit added, ultimately to be changed to the next release...:-))

Best wishes to all

John
