Hello List, I have some plots with the wireframe() function, and I'd like to display them in a single jpeg file. I know that par(mfrow=c(x,y)) will divide my display window in x rows and y columns, and although this works with plot(), it looks like it's not working with wireframe. here's my code: library(lattice) library(Cairo) CairoJPEG("wiley-rank.jpeg", width=960,

Dear List, my problem should be easy to fix, but I couldn't find a solution by myself... In my survey, there is a question with 14 possible answers.

Dear R-Experts, I have an empirical dataset with 150 subjects for 24 observations. In each observation, each subject can have a score in the range 0:3. I made then a simple index making the sum of the values in each row, so each subject have a score between 0 and 72. I was thinking about what kind of theoretical distribution such an index should have, so I try to make things random like:

Do anyone know anything about the use of R for agent-based social simulation? It should be possible, and would be convenient for the simple reason that there are several nice packages containing useful stuff for SNA (Social Network Analysis). Information about packages, web sites, experienced persons in the field, etc. would be very welcome. Tom
