>R is extremely slow at a lot of tasks, for one thing, even more than Python.

Base R is quite slow. R + data.table is faster than Python + Pandas in a benchmark that I did recently.

For a 1 million row CSV file, Read + Sort + self-Join + Write took on a Windows box:

Base R: 47.56s

Python + Pandas: 6.44s

R + data.table: 2.99s

Oops. That was meant to be a comment on the 'Every modeler is supposed to be a great Python programmer' thread.
