Hi everyone, I have a formula like this: f <- as.formula(y ~ p0a * exp(-0.5 * ((x - p1a)/p2a)^2))
I would like to "dynamically" provide starting values for p0a, p1a, p2a. Is there a way to do it? #Params estimates p <- c(12, 10, 1) # This is where I have difficulties mystart <- substitute(...) nls(formula = f, start = mystart) Regards, Philippe [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
