[R] fitting non linear data

[Jesus Frias]

Gregory,

    Please have a look at the library nls (it comes with the base
distribution of R).

    You'll find a good example in

http://cran.r-project.org/doc/manuals/R-intro.pdf (pp 62 is for nonlinear
least squares).

    You can use that document and the rest of the manuals at

http://cran.r-project.org/

 to guide yourself up through R.

best regards,

IOsu
