[R] repeated measures with random effects

[Spencer Graves]

	  Have you tried 'RSiteSearch("repeated measures with random 
effects")'?  I just got 74 hits, some of which might interest you.

	  Also, have you reviewed Pinheiro and Bates (2000) Mixed-Effects 
Models in S and S-Plus (Springer)?  This book, the lme function in 
library(nlme) and the more recent lmer and lme4 / Matrix packages, are 
to my knowledge the state of the art in this area.

	  In addition, have you read the posting guide 
(www.R-project.org/posting-guide.html)?  People who follow that guide, I 
believe, tend to get quicker, more useful replies.  In particular, I've 
looked at your post several times since it appeared and each time 
decided not to reply, because I didn't have the time I thought it would 
take to offer a useful reply.  If you had included more complete example 
that I could have copied into R and tried -- possibly with alternatives 
-- in less than, say, 40 seconds, I might have more useful comments for 
you and might have replied sooner.
