"R Packages" by Hadley Wickham, Abridged

R Packages, Abridged

Consider completing "Advanced R, Abridged" and "Git 101 Exercises" first.

"Advanced R" by Hadley Wickham is widely considered the best resource to improve your knowledge at building an R package. This guide is designed to give you the most essential parts of R Packages so that you can get going right away. It still will take a long time, but not as long.


  1. Read the following chapters of "R Packages" by Hadley Wickham:

Advanced R, Abridged

"Advanced R" by Hadley Wickham is widely considered the best resource to improve your knowledge at R. However, going through it and answering every exercise takes a long time. This guide is designed to give you the most essential parts of Advanced R so that you can get going right away. It still will take a long time, but not as long.


1.) Quickly skim these chapters (without doing the exercises) to make sure you're familiar with the concepts:

Git 101, with Exercises

Git is the key tool we use to allow multiple people to work on the same code base. Git takes care of merging everyone's contributions smoothly. Hence, learning how to use Git is critical to contributing to open source.


Exercise 1: Go through the Try Git Guide

Exercise 2: Learn How to file a github issue.

How to modularize your py.test fixtures

Using py.test is great and the support for test fixtures is pretty awesome. However, in order to share your fixtures across your entire module, py.test suggests you define all your fixtures within one single file. This is impractical if you have a large quantity of fixtures -- for better organization and readibility, you would much rather define your fixtures across multiple, well-named files. But how do you do that? ...No one on the internet seemed to know.

Turns out, however, you can define fixtures in individual files like this:


import pytest

You can’t perform that action at this time.
