Hi Martin,

You wrote in your response,

  ... Anyway, here we've used the new lmer2(...., sparseX = TRUE)
 code in the not-released,  but Rforge-available  "lme4a" package
 ("a" : was formerly called "allcoef"-branch of lme4).
 which did allow to circumvent memory problems, as now,
 both X (fixed effects) and  Z (random effects)  where sparse
 matrices.

I went to Rforge and see a listing for lme4a, but when I try

*install.packages("lme4a", repos="http://R-Forge.R-project.org")*
**
*
I'm told

**"In getDependencies(pkgs, dependencies, available, lib) :*
*package lme4a is not available"*
**
*
I saw the note from 2009-07-28 that lme4a had been combined with lme4.
However, the date on lme4a postdates that note (2007-08-07), so I'm a little
confused.  What's the best way to access the code that uses sparse matrices
for the fixed effects also?

Thanks in advance - Pete
