Let’s Have Some Sympathy For The Part-time R User

When I started writing about methods for better "parametric programming" interfaces for dplyr for R dplyr users in December of 2016 I encountered three divisions in the audience:

  • dplyr users who had such a need, and wanted such extensions.
  • dplyr users who did not have such a need ("we always know the column names").
  • dplyr users who found the then-current fairly complex "underscore" and lazyeval system sufficient for the task.

Needing name substitution is a problem an advanced full-time R user can solve on their own. However a part-time R would greatly benefit from a simple, reliable, readable, documented, and comprehensible packaged solution. Continue reading Let’s Have Some Sympathy For The Part-time R User

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).

To illustrate this we will work an example.

seplyr update

The development version of my new R package seplyr is performing in practical applications with dplyr 0.7.* much better than even I (the seplyr package author) expected.

I think I have hit a very good set of trade-offs, and I have now spent significant time creating documentation and examples.

I wish there had been such a package weeks ago, and that I had started using this approach in my own client work at that time. If you are already a dplyr user I strongly suggest trying seplyr in your own analysis projects.

Please see here for details.
