In that case you should look to ?nls or maybe ?optim Regards Petr > > Paola. > > > > On Fri, Aug 5, 2011 at 2:55 PM, Petr PIKAL <petr.pi...@precheza.cz> wrote: > Hi > > > > Dearl all, > > > > I have to fit a function > > > > y = f(x1, x2) > > to data experiemntal data describing the measured behavior of y. > > > > x1 and x2 are the independent variables. > > > > Could you suggest me wich R package can I use for this purpose? > ?nls > ?lm > ?loess > ?glm > > And there are plenty more if you do not stick to base packages.
