Thank you Basically I have a rectangular space (like an aquarium) in which I made some analysis. I can make
image(lat, long, value) for each height but what I dream about is to make something like scatterplot3d(lat, long, height) with points set according to a value. Up to now i can do scatterplot3d(sloupecn, radan, vrstvan, color=as.numeric(cut(value, c(0, 100, 400, 1000)))) which will give you green and red points in upper right corner. I started to try to make cex.symbols scaled according to value too but up to now I did not manage to work correctly. in scatterplot3d(sloupecn, radan, vrstvan, cex.symbols = value/max(value)+2, color=as.numeric(cut(value, c(0, 100, 400, 1000)))) the biggest points are at other places then I expected. here are the data vrstvan sloupecn radan value 1 4 1 73.8 1 4 9 54.9 1 4 17 72 1 1 1 96 1 1 9 52.1 1 1 17 53.3 4 4 1 58.4 4 4 9 93.5 4 4 17 140.2 4 1 1 90.3 4 1 9 36.5 4 1 17 55.1 7 4 1 169.1 7 4 9 718 7 4 17 813 7 1 1 73.4 7 1 9 46.5 7 1 17 205 Petr [EMAIL PROTECTED] "hadley wickham" <[EMAIL PROTECTED]> napsal dne 10.01.2008 16:07:31: > On Jan 10, 2008 8:36 AM, Petr PIKAL <[EMAIL PROTECTED]> wrote: > > Dear all > > > > I want to display 4 dimensional space by some suitable way.
