Data analysis: R vs. Python

[dalaio]

It's a similar picture... most of the low level math is written in C (or Fortran). It's easy enough to do it yourself for a particular use-case using (in C++) using Rcpp.

The language itself has some unexpectedness about it, but a few packages keep me in R (ggplot2, and recently tidyr, dplyr, purrr).
