I am new to R and would like to get some practice analyzing multilevel data. I wonder if anyone can point me to a sample data set and command lines that I might replicate for a sample session. I would then compare my output with HLM output. Any help is appreciated. ------ Harold C. Doran Director of Research and Evaluation New American Schools 675 N.

There are examples in the scripts for the nlme package, and in the scripts in the MASS package, Both are installed in R, and even cover educational data.

Dear Harold, You might take a look at the appendix on mixed-effect models to my R and S-PLUS Companion to Applied Regression; the appendix is available at <http://socserv.socsci.mcmaster.ca/jfox/Books/Companion/appendix-mixed-models.pdf>. I hope that this helps, John At 12:31 PM 4/8/2003 -0400, Harold Doran wrote:>I am new to R and would like to get some practice analyzing multilevel >data.
