[R] package nlme: covariates and self-starting nonlinear regression
Dear all, I want to include covariates into the self-starting linear regression functions SSbiexp and SSfol. Is there a way to do this or do I need to define my own functions depending on the covariates? My second question concerns the function nlme: Is it possible to use this functions for fixed effects only? Thanks a lot for your help Best regards Peter -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
