Debian Packages:
r-base
ess
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')
|
The package will be downloaded and installed into
/usr/local/lib/R/site-library. This can live comfortably with
the Debian installed packages which live in
/usr/lib/R/site-library. The only problem is that a package
for Debian may come out and you will end up having duplication.
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 79.1.
