This repository contains most of the materials used in the introductory and advanced classes to R at Westat.
The scripts are provided in Rmarkdown with a markdown output. The scripts are grouped by topic and do not correspond to individual classes.
The class covers the fundamentals of the language and some data manipulation (split-apply-combine, merging, reshaping). It is oriented towards an audience with previous experience in statistics but no background (or interest) in computer programming. The goal of the class is not only to provide participants with the ability to run studies in R but also to understand enough about the language so that they can then explore new features on their own.
The class was designed for a 3-day intensive seminar and includes a number of exercises designed to cover a few details that are left out from the main lecture and to encourage the participants to use the excellent documentation and community-maintained resources available to R users.
The class is adapted to the necessities of statistical programmers and covers object-oriented programming using S3 and S4 classes and package development.
The class draws heavily from:
- The Art of R Programming, by Norman Matloff
- Advanced R Programming, by Hadley Wickham.
