| <h2>Introduction</h2> |
| |
| <p><b>R</b> is a computer language not entirely unlike the S |
| language developed at AT&T Bell Laboratories by Rick Becker, |
| John Chambers and Allan Wilks. The two languages are implemented |
| quite differently, but bear enough superficial resemblance that |
| users should be able to switch between the two with relative ease. |
| Currently the software is undergoing active development. Discussion |
| of the development process is carried out on the "r-devel" mailing |
| list. See the <a href="resources.html">resources page</a> for |
| details on how to subscribe to this list.</p> |
| |
| <p>We have implemented <b>R</b> in what we hope is a very portable |
| fashion and in way which requires relatively little in the way of |
| machine resources. Implementations exist for many for many members |
| of the Unix family of operating systems, including <b>AIX</b>, |
| <b>FreeBSD</b>, <b>GNU/Linux</b>, <b>HPUX</b>, <b>Irix</b>, |
| <b>macOS</b>, <b>Solaris</b>, and <b>Tru64</b>. In addition there |
| is a version for <b>Microsoft Windows</b> (9x, ME, NT4, 2000, |
| XP).</p> |
| |
| <h2>Present Status</h2> |
| |
| The present version implements most of the functionality in the |
| 1988 S book (the "Blue Book") and many of the applications. In |
| addition, we have implemented much of the functionality from the |
| 1992 S book (the "White Book"). In particular we have versions of |
| "lm", "glm", "aov" and "loess", and versions of "gam" and "tree" |
| are available in contributed packages. There are several manuals in |
| the distribution, plus a comprehensive set of help pages in "output |
| independent" form which can be used to create versions for HTML, |
| LaTeX, text, PDF etc. |
