Wanted: cdata Test Pilots

I need a few volunteers to please “test pilot” the development version of the R package cdata, please.

Jackie Cochran at 1938 Bendix Race
Jacqueline Cochran: at the time of her death, no other pilot held more speed, distance, or altitude records in aviation history than Cochran.

Data Reshaping with cdata

I’ve just shared a short webcast on data reshaping in R using the cdata package.

We also have two really nifty articles on the theory and methods:

Please give it a try!

This is the material I recently presented at the January 2017 BARUG Meetup.

More documentation for Win-Vector R packages

The Win-Vector public R packages now all have new pkgdown documentation sites! (And, a thank-you to Hadley Wickham for developing the pkgdown tool.)

Please check them out (hint: vtreat is our favorite).
