Plotting the complex fft in 3D?

Hello, I'm new to R (using it since about two weeks), but absolutely a fan of it from the beginning on. :-) Best tool for working with data I found. :-) I tried using the fft() and other funcitons for analysing time series. What I would be glad to have, would be a convenient way to display the complex result of a fft in a way, that real and imaginary parts each use an axis for themselves, and the index of the resulting values use the third axe. When displaying this as a 3D->2D picture, it also would be nice, to change the view, like it can be done with persp(). Is there already a package or script for preparing the data of an fft to be displayed in this way?
I don't find this very enlightening, but here you go: x <- rnorm(1000) f <- fft(x) library(rgl) plot3d(1:length(f), Re(f), Im(f)) Duncan Murdoch
