I am attempting 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

I have set up Samba so that all users on my small network can read from my one of my Linux shares as well as write to that share. However, when user A saves a file to that share, user B can't open it -- and vice versa. How can I set up samba so that all files written to that share can be read, modified, and deleted by all users? Thanks in advance for an answer to this question.
