Hi, I uses R mainly for the visualisation of data (persp,contour, ...) and have the following problem: I have a spherical symmetric object (values only depend on the radius) where the funcion f(radius) is not known exactly. My table looks like this: radius value 0 5 0.5 4 1 3.5 ... ... How can I plot these table with persp()? Is there a function which generates me an array (in the x-y-plane) for an 3d-Plot?
