Hi, I'm terribly sorry for submitting my primitive question, I'm a beginner in R and was hoping to get some help re: non-linear fit. I have a 2D data with the following structure: A B C 1 1 111 1 2 121 1 3 131 2 1 141 2 2 151 2 3 161 3 1 171 3 2 181 3 3 191 I'm trying to fit C = non-linear function (A,B). I was wondering if there's a package that would save my time of doing direct least square estimation. Thank you, Diana
If your "non-linear function (A, B)" is parametric nls should do it
for
you. If you have R version 2 (perhaps even 1.9) do ?nls to see the help
page. Older versions of R require library(nls) first.
Hope this helps,
Andy
