Dears, I saw in the R-project site some R-books. However, I'm new in this community and I didn't figure out what are the best books. Can you suggest me some "reference" books? My intentions with R is concerned to Artificial Intelligence simulations, Classification and general Statistics (e.g., regression, multivariate regression, etc). Thanks for any help, Anderson

I am working on a project that requires me to do very large factorial evaluations. On R the built in factorial function and the one I created both are not able to do factorials over 170. The first gives an error and mine return Inf. Is there a way to have R do these larger calculations (the calculator in accessories can do 10000 factorial and Maple can do even larger) -- View this message in
