| R: Statistical Software | 
There is an excellent selection of very high quality statistical software available for Debian GNU/Linux. A favourite is R, an open source version of S/SPlus, widely used in the academic statistical community.
The R packages from CRAN (the Comprehensive R Archive Network) are packaged in quite a collection for Debian (but not all are included yet), and you may want to pick and choose, or just install the whole lot:
| $ wajig install `wajig listnames ^r-` | 
See the Data Mining Survivor for examples of using R.
R itself also has a package management facility and you can install packages directly from CRAN:
| 
  > install.packages('ellipse')
 | 
Emacs, provided by the emacs21 package,
with the additional ess package, provides an excellent
interface for working with R. To get started within emacs, simply
issue the command M-x R enter
. This will ask for a
starting data directory which defaults to the current working
directory (if you simply press 
enter
 again). 
Alternatively, load in a file with a .R extension and the R mode will
be loaded. You will have a collection of convenient R buttons added to
your button bar, as in Figure 73.1.
