arrow Discovering the benefits of R

arrow Identifying some programming concepts that make R special

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.

Some people would argue — and we think they’re right — that R is much more than a statistical programming language. It’s also

  • 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
  • A versatile toolbox for extensive automation of your work

In this chapter, we fill you in on the benefits of R, as well as its unique features and quirks.
