Re: [R] 2-dim density plot

I'd suggest either a color plot as given by image() and related functions or a 3d mesh-plot which you can get from persp() E.g., x = seq(0,1,by=0.01); y = x z = outer(x,y+1,"/") # z = x/(y+1) -- I know that's not a density but you can adapt as necessary filled.contour(x,y,z) persp(x,y,z) There
