[R-SIG-Finance] [R-sig-finance] Plot TS-matrix as a surface

[Jeff Ryan]

PS,

I have been working on adding a chartSeries3d function to quantmod.
The code isn't in place yet, but it relies on persp, and some extra
manipulation to offer much better axis labeling.  It is designed for
xts/zoo structures in particular.  The final code will work for any
time-series.

This should be in the next release of quantmod, but I've posted the
alpha code and a .png here:

HTH,
Jeff
