Indian Men are not Rapists

Given what a beautiful and mature functional programming language R is, there is a surprising, though understandable, lack of visibility of functional programming techniques in R. I recently gave an introductory talk about it in Mumbai R Meetup group.

The presentation accompanying the talk can be found here - . All the code discussed in the talk is included in the slides.

If you would like to hone your functional programming skills in R, I have a suggestion to make - read R code. As an example, you can start by reading through the codebase of ggplot2 (and possibly anything else written by Hadley Wickham).

In this space, I hack together with ingredients and recipes to make data science.
