[R] Problems using lmer {lme4}

2013-05-17 Thread Andrea Goijman
Dear R list, I'm attaching a sample of my data which consists on the presence/absence (punto6, binomial n=5 occasions) of different species (sp), on different sites (site) within routes ('route). First, I want to be able to find if there is autocorrelation of the response variable between the

It would be better to post this on the r-sig-mixed-models list, I think. -- Bert On Fri, May 17, 2013 at 10:02 AM, Andrea Goijman agoij...@cnia.inta.gov.ar wrote: Dear R list, I'm attaching a sample of my data which consists on the presence/absence (punto6, binomial n=5 occasions) of

Hi Patrick, Thanks for you reply. I tried adding site fixed effect as you told me, but the program failed again (R stopped working). Basically, what I am trying to do is to test for auto-correlation between sites within routes. My survey takes place in routes, but each route is divided in
