Dear R Users, Beginners and Experts, I want to fit to my data an exponential function with following functional form: y=exp(a*x)
I used the function "nls" but this gives me exponential fits with following functional form: y=l*exp(a*x) With "l" being an scaling factor. What do I need to change in my R code? t.dataFitModel=nls(t.dataForFitY ~exp(a*t.dataForFitX), data=t.dataForFit, start=list(a = 0.01242922), trace=TRUE, algorithm = "plinear") Thanks in advance and a nice weekend, Henri ______________________________________________ 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.
