Hi all,
I have some difficulties to work with the function lmer from lme4
Does somebody have a tutorial or different examples to use this function?

Hello, list
why not add the smart proposal by Greg Snow as a built-in function in
{stats},
just changing the "x234" and "newc" lines to allow for more
distributions to be generated ?
Or do I miss an already existing function to do that ?

Thanks a lot, really, Philippe, for this explanation... and sorry for

Of course your guess is right : I turned to French (and "forgot" to
