[R] 3d surface plot (ideally using rgl package)?
Dear HelpeRs,
I would be grateful for anybody who might help to produce the following
plot (the code for matlab is below) using the "rgl" package of R?
[t,r] = meshgrid(linspace(0,2*pi,361),linspace(-4,4,101));
[x,y] = pol2cart(t,r);
P = peaks(x,y);
figure('color','white');
polarplot3d(P,'colordata',gradient(P));
view([-18 72]);
You may see the code and plot output at:

Many Thanks
A.

It is by no means clear what the "peaks" function does or if it has any R equivalent, but perhaps looking at demo(rgl) will get you started. After that, you should probably show what you've tried (at least as far as replicating the calculation aspects).
