[R] Reproducing a 3d yield curve plot from New York Times

[David Winsemius]

At the bottom you asked for package recs:

Karline Soetaert's (excuse any misspelling) plot3D package should be examined.

I didn't find the fine-grained example that I remember seeing but this is an example in RGL code:

I'm interested in figuring out how to smooth the color transitions, add the grid/gridlines and use a different set of color gradients when the values are negative.  Also, I realize that my colors transition along the wrong axis (1m, 3m, etc) rather than along y.

I'm reasonably sure that MatLab has a function for this sort of dispaly and requests for duplicating it with R facilities have been satisfied.
