Sarah, I have 669 sites and each site has 7 years of data, so if I'm thinking correctly then there should be 4683 possible combinations of site x year. For each year though I need 3 sampling periods so that there is something like the following: site 1 year1 sample 1 site 1 year1

Yeah, that's tiny: fullout - expand.grid(site=1:669, year=1:7, sample=1:3) dim(fullout) [1] 14049 3 Almost certainly the problem is that your expand.grid result doesn't have the same column names as your actual data file, so merge() is trying to make an enormous result. Note how when I
