The Google Summer of Code (2012) project to extend xts has produced a very promising new plot.xts function. Michael Weylandt, the project’s student, wrote R-SIG-Finance to request impressions, feedback, and bug reports. The function is housed in the xtsExtra package of the xts project on R-Forge.
xtsExtra::plot.xts and let us know what you think. A sample of the eye-candy produced by the code in Michael’s email is below. Granted, this isn’t a one-liner, but it’s certainly impressive! Great work Michael!
