...g windows XP. I would like to keep one window- command line in one monitor and the script and graphs in the second monitor. How do I set it up? It works for word documents simply by dragging the document. It does not work if I drag and drop the scripts window. Is R not compatible for this? Thanks.

Hi,In SPlus, I use the function 'cluster' with GLM to adjust for correlated errors within a cluster ( e.g. cluster(ID)) as a covariate. Is there a similar function in R to use with GLM ?
