[R] how to find a function for plotting polygon surfaces: polgon3d(xc, yc, obs)

I have set of n coordinates xc, yc (but not a grid!) and n observations obs at these points. Where to find a simple plot function (3D perspective) that plots a polygon (alternative: just segmented points over a map, as eg in library maps). rgl.surface(xc,yc,obs) is not working. Thanks W.Polasek

[R] flexible contour plots

I want to make a contour plot estimate based on a sample of points -- a sort of smoothing.in 2D (but also in a scatterplot)? Any ideas [[alternative HTML version deleted]] __ R-help@r-project.org mailing list
