Hi, I think do you need use drc package: drc: Analysis of dose-response curves Analysis of one or multiple curves with focus on concentration-response, dose-response and time-response curves used, for example in biology, environmental sciences, medicine, pharmacology, toxicology. -- Bernardo Rangel Tura, M.D,MPH,Ph.D National Institute of Cardiology Brazil ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
