Getting starts with R:

If you are not familiar with R, see the following resources on the www.r-project.org website:

  • An Introduction to R (PDF, approx. 100 pages, 650kB), based on the former "Notes on R", gives an introduction to the language and how to use R for doing statistical analysis and graphics.
  • A draft of the R language definition (PDF, approx. 60 pages, 400kB) documents the language; that is, the objects that it works on, and the details of the expression evaluation process, which are useful to know when programming R functions.
  • Writing R Extensions (PDF, approx. 85 pages, 500kB) covers how to create your own packages, write R help files, and the foreign language (C, C++, Fortran, …) interfaces.
  • R Data Import/Export (PDF, approx. 35 pages, 270kB) describes the import and export facilities available either in R itself or via packages which are available from CRAN.
  • R Installation and Administration (PDF, approx. 30 pages, 200kB).
  • The R Reference Index (PDF, approx. 2200 pages, 12MB) contains all help files of the R standard and recommended packages in printable form.
