This page records the third edition's place in the Political Analysis series. The fourth edition is the current edition: visit its page for book information and current teaching and learning resources.
The R Companion brought the Political Analysis series' emphasis on learning by doing to R: guided examples, annotated screenshots, and reusable scripts helped students connect research methods with political questions.
Published in 2022, the third edition expanded the book to 15 chapters and bundled its functions and political datasets in the RCPA3 package. Its coverage extended from descriptive statistics and visualization to inference, regression, and independent research.
RCPA4 continues that approach with revised content and updated datasets. It is the edition to explore for new courses and current resources.
