An Introduction to R

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 dynamically loaded modules written in C, C++ or Fortran. One of R's strengths is the ease with which well-designed publication-quality plots can be produced.

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.

This is a printed copy of the tutorial manual from the R distribution, with additional new examples, notes and corrections added by the publisher (second printing, September 2004). All the money raised from the sale of this book supports the development of free software and documentation.
