...empting to set up a mixed effects model, with one factor fixed (put in as.factor, with three factor levels) and one factor random(put in as.factor, with four different batches) as well as the interactions. I have tried the lme function, but R continues to crash everytime I run it... My code is: model_lme(y~a,random=~b+a:b) Is this way off base? I just need to get F statistics to do hypothesis testing. Thanks, Chris

1. If your code actually runs, you should upgrade R, and quit using `_' for assignment... 8-) 2. You seem to have an extraneous `]' after the na.exclude. Could that be the problem?
