Hello. Does anoby know if it's safe to run two instances of R (in R CMD BATCH mode) in the same directory ? If so, is it safe to run them on different computers (with access to the same filesystem via NFS) ? Thanks.

I was wandering if anybody ever tried to compare the classification accuracy of nnet to other (rpart, tree, bagging) models. From what I know, there is no reason to expect a significant difference in classification accuracy between these models, yet in my particular case I get about 10% error rate for tree, rpart and bagging model and 80% error rate for nnet, applied to the same data. Thanks.

Hello. I have some trouble with mixed effects in R, similar to problems that other people had with not nested models and lme, as I understand from the mailing list archive. Unfortunately, I could not understand the solutions that were proposed... I have a data set with response variable (y) and two explanatory variables x1 and x2 (x1 - fixed factor, x2 - random factor). Fixed factor x1 is
