Dear All,
The function curve() draws the graph of functions from R to R. Is
there some homologous function to curve() to draw functions from R^2
to R?
No, you would have to write it yourself. The basic idea is to use
outer() to construct a matrix of function evaluations, then plot the
matrix using persp, contour, image, rgl::persp3d, etc. There are
examples on the ?contour man page.
