With an estimated worldwide user base of more than 2 million people, the R language has rapidly grown and extended since its origin as an academic demonstration language in the 1990s.

  • A very powerful tool for all kinds of data processing and manipulation
  • A community of programmers, users, academics, and practitioners
  • A tool that makes all kinds of publication-quality graphics and data visualizations
  • A collection of freely distributed add-on packages
