Hi Jim, Thank you very much for your help. It is much appreciated. Bert, the reason I didn't ask someone at work is because none of us knew. The person I referred to in my email thought it might be possible but didn't know how. I can now inform everyone. Thanks, Laura On Wed, Oct 29, 2008

you 'll may be interested in the drc package (a quick start would be http://www.bioassay.dk), where you get some nice plots and can fit appropriate models as well - very handy if you want to estimate effective doses. hth. Laura Bonnett schrieb: Hi Everyone, I have data in a long format
