It would be nice to also have some notes about performance of both the languages for each of the tasks compared. I believe pandas would be faster due to its implementation in C. The last time I checked R was an interpreted language with its interpreter written in R.

And like pandas, many of the performance bottlenecks in R have been re-written in C. See dplyr and data.table for packages that solve a similar problem to pandas with similar speed (and for some scenarios they're actually faster!)

Looks interesting! Thanks for the information.
