A student here has been getting a bit irritated with some side effects
of scale() (OS is Windows XP, the behaviour occurs in R 2.0.0, but not
1.7.1). The problem is that she scales a variable in a data frame, then
does a regression, and tries to get some predictions for some new data.

developing Bassist again. Actually, Bob O'Hara (who usually calls
himself Anon. in this list) should know more, and hopefully this

I've got a colleague who's using a GLMM to analyse her data, and I've

I have a problem where I want to find the ML estimate of a discrete
parameter. I just want a function like optim that finds the max/min
value for a function. Does anyone know of such a function for R?
Thanks.
