page	Intermediate R for reproducible scientific analysis

Intermediate lessons for researchers already familiar with R, but not programming concepts.

The goal of this lesson is to teach researchers already experienced with R some useful programming concepts that will make writing code more efficient, modular, and reusable, as well as packages for efficient data analysis.

A variety of third party packages are used throughout this workshop. These are not necessarily the best, nor are they comprehensive, but they are packages we find useful.

Note that this workshop will not cover statistics.
