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. Please try 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!
quantmod, TTR, and xts were (not so) recently featured on the Inference for R Blog. Inference for R is a Integrated Development Environment (IDE) designed specifically for R. The post gives an example of how to easily perform advanced financial stock analysis using Inference in Excel. I appreciate how they’re making R more accessible to a general audience, even though I like a command line interface and my preferred development environment is vim.
