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.

Dear R-users, I use R to run spatial stuff and it takes up a lot of ram. Runs can take hours or days. I am thinking of getting a new desktop. Can R take advantage of the dual-core system? I have a dual-core computer at work. But it seems that right now R is using only one processor. The new computers feature quad core with 3GB of RAM. Can R take advantage of the 4 chips? Or am I better off

Also, it would be really if nice the "by=..." was included in the output of the plot.gam() and the "Approximate significance of smooth terms:" part of the summary.gam(). 2. John Fox has modified anova.glm() into anova.gam() (http://www.socsci.mcmaster.ca/jfox/Books/Companion/nonparametric-regression.txt) for comparison of two or more fitted models based on the difference between residual deviances. Indiscriminate use of such a procedure shouldn't perhaps be encouraged, but I think that many users expect it to be part of the mgcv...

The R-Commander menus are easily configurable through a text file. The menu tree and additional information are available at <http://www.socsci.mcmaster.ca/jfox/Misc/Rcmdr/>. The menus lead to simple dialog boxes, the general contents of which are more or less obvious from the names of the menu items.
