R is a language and interactive environment for statistical computing, data analysis, and graphics. It provides a wide variety of statistical techniques including linear and nonlinear modeling, time-series analysis, classification, and clustering, along with a powerful system for producing publication-quality plots and visualizations.
The interactive console supports exploratory data analysis with immediate feedback, while scripts can be executed non-interactively via --file or through the companion Rscript command. R's package ecosystem on CRAN offers thousands of contributed libraries extending its capabilities across fields from bioinformatics to econometrics. The workspace system saves objects between sessions, though --no-save and --vanilla flags allow clean stateless execution for reproducible workflows.
