plot.xts will be removed from xtsExtra in the near future.  Yes,
plot.xts and supporting function now in xts-proper supercede the
plot.xts in xtsExtra.

We use this code for production-critical tasks every day.  

The core of xts has the usual smattering of optimizations and bug fixes,
and has not changed substantially from a user perspective.  

plot.xts is substantially different from the old plot.xts, but the old
plot.xts didn't do much, which is why most users used chartSeries or

As always, YMMV, but this code has been under development and in use for
over a year, and I at least consider it stable and ready for prime time.
