Re: [R] 3D-plots of 2D-grids

Hello David, thanks again for your reply. Two things remain unclear. That the data is disjointed is ok, as there are only values in hectares, where there are actually buildings and stuff, forest/nature is NA. The presp-scan that I get from persp(grd) has no similarity to the image in 2d. My gues

Hello everybody, I have an Ascii-grid (100x100m) with population density over Switzerland (local coordinations system, CH LV03). Now I would like to have a nice graphic to present the data. I would like to make a plot that will show the density as the z-variable and raise for example a stacking p
