You probably want function persp3d() in package rgl. You have to define the formula as a function and specify the limits correctly, but you were close:

I've been pointed in the direction of plot3d(), so the command is something like plot3d(x^2+y^2,(x,-3,3),(y,-3,3)). And a smart person out there is going to tell me where this syntax comes from (or belongs to), there is also a R package called MapleSoft ( I believe) which is commercial, and there is always Mathematica. So is there a R function to plot z=f(x,y) without obtain or generating data.
