I presume this about the CRAN binary packages for R and Cairo (from
CRAN, not BioC), in which case you should have asked on R-sig-mac.
But the likely answer is that you forgot to install X11 via XQuartz.
See the 'R Installation and Administration Manual', and if you need more
help, use R-sig-m

Dear Christoph,
I don't see how what you suggest can work in a mixed-effects model.
In the case you originally raised, of independent observations, you should be
able to recover the coefficients for the multinomial logit model by fitting the
logits that I suggested in my earlier email, but not

Dear John and R-helpers,
Thanks for your replies that were both very helpful.
The reason I was asking is that I´m searching for an easier way to

I was hoping that *combinations of binomial glmmPQL or lmer calls* might

For speed your best choice is probably to load your data into a
database, then pull your samples from the database. A simple database
is SQLite and there are R packages that work directly with that
database.
Can the later samples contain some of the same rows as previous
samples? Or once a row i

Hi,
I'm pretty sure you posted this exact question already. Usually if you
don't get any replies, it means your question is badly-formed. Posting
the same thing won't help any. Posting a revised version might.
