...eved but the methods used don't work for me. I won't pretend I understand linux or samba permissions because every time I think I've got it, I turn out to be wrong. So here goes. Let's say I have 3 users & 2 groups. each group has it's own directory. user1 is a member of grpA & grpB (needs rwx access to grpA & grpB directory & all files). user2 is a member of grpA (needs rwx access to only grpA directory & all files. user3 is a member of grpB(needs rwx access to only grpB directory & all files. When a user creates a file I want the file to have -...

I have not really used lm before and I was hoping for some help on a simple problem. Here is a toy version of the problem I want to solve. y x grp -.9 1 a -.8 2 a -.7 3 a -.7 1.5 b -.5 2.5 b -.3 3.5 b -.19 2.7 c -.11 3.7 c -.41 4.7 c I want to fit a model that has one y-intercept and three slopes, one for
