Hi all, I would like to ask that is there any function in R which can solve nonlinear system equations with several variables. Thats mean some functions similar to the 'fsolve' or 'fzero' in matlab.

Have you considered "optim" in the MASS library? Also, have you tried www.r-project.org -> search -> R site search? hope this helps. spencer graves Wong Jerry wrote:> Hi all, > > I would like to ask that is there any function in R which can solve > nonlinear system equations with several variables.

This is (incomplete) port of Minpack Fortran library and it now contains only one function FSolve(fun,guess) which do exactly what you have requested. Comments welcome.
