R workshops

Four workshops, in the order to take them:

1. R Introduction: objects, functions, packages, reading data, basic data manipulation and graphs. For people new to R.
2. R Regression Models: the formula interface, model summaries and predictions, contrasts, and clustered data. Intermediate.
3. R Graphics: ggplot2 from aesthetics to themes. Intermediate.
4. R Data Wrangling: iterating over files, writing functions, regular expressions, reshaping. Intermediate to advanced.

Before any of them, follow the installation page. Each workshop’s page links to its materials (data, cheat sheets, a BLANK file to type along in, and the exercise solutions).
