This tutorial manual provides a comprehensive introduction to R, a software package for statistical computing and graphics.
R supports a wide range of statistical techniques, and is easily extensible via user-defined functions written in its own
language or using C, C++ or Fortran. One of R's strengths is the ease with which well-designed publication-quality plots can
be produced. This is a printed copy of the tutorial manual from the R distribution, with additional examples, notes and corrections.
It is based on R version 2.9.0, released April 2009. R is free software, distributed under the terms of the GNU General Public
License (GPL). It can be used with GNU/Linux, Unix and Microsoft Windows. All the money raised from the sale of this book
supports the development of free software and documentation.
