A guide to R packages for Ubuntu

If you want additional packages (over 1,100), you can check out my
cran2deb4ubuntu PPA:

https://launchpad.net/~marutter/+archive/c2d4u

In theory, this PPA has all the packages listed in the CRAN Task Views and
any dependencies. ?In practice, is has about 98% of them, as some packages
have issues.

As per a request, here is a brief guide to what is available to R 
users as packages in Ubuntu.

Each release of Ubuntu includes the latest version of R and the 
recommended packages.  In addition, there are approximately 80 
additional r-cran packages available in the default repositories.  The 
limitation to these packages is that they are not updated and reflect 
the current version of the program or package when that version of 
Ubuntu was released.

If you want to have current versions of R and the recommended 
packages, there are two repositories to choose from:

CRAN: http://cran.r-project.org/bin/linux/ubuntu/
Launchpad PPA: https://launchpad.net/~marutter/+archive/rrutter

Both sites have the same packages (the PPA packages are mirrored on 
CRAN), but there may be a reason to use one over the other.

CRAN Advantages:
- A local mirror may be faster in terms of internet speed.
- Older versions of the packages are available, so if an update to R 
or a core package breaks your code, you can reinstall an older version 
via synaptic or apt.

PPA Advantages:
- Quickest way to get the updates (only by about 24 hours however)
- Easy to install (sudo add-apt-repository ppa:marutter/rrutter)

If you have been using CRAN, then there is no reason to change to the 
PPA, as the same packages is provided at both locations.  I will 
continue to maintain both sites, so no need to worry about one or the 
other going away.

If you want additional packages (over 1,100), you can check out my 
cran2deb4ubuntu PPA:

https://launchpad.net/~marutter/+archive/c2d4u

In theory, this PPA has all the packages listed in the CRAN Task Views 
and any dependencies.  In practice, is has about 98% of them, as some 
packages have issues.  These packages can be installed via synaptic or 
apt (sudo apt-get install r-cran-ggplot2, for example).  The main 
advantage of this approach is that tricky Ubuntu package requirements 
will automatically be installed when installing the package.  They 
will also be automatically updated during normal Ubuntu updates, which 
is another advantage.  These packages are NOT installed when a 
install.packages("foo") command is used from within R.

One of my plans this summer/sabbatical is create documentation for the 
cran2deb4ubuntu project and give more information about what is and 
what is not available.

If you have any further questions, please let me know.

No need, but see above and understand what .libPaths does. It's all
documented and has been answered before, eg

Is there a reason to limit 'cran2deb4ubuntu' to Task Views packages?
For example, I would like to install all the Rcmdr plug-ins via the
PPA but the only one available is 'rcmdrplugin.doe'. Very useful GUIs
such as 'playwith' and 'latticist' are missing, too. Even some popular
toolkit deps are missing: 'gwidgetstcltk'. Are there plans to increase
the number of packages provided?

I had to draw a line somewhere. ?Maintaining all the packages was out of the
question, as the number is just too high. ?Since there is no list at this
time of the most popular packages, I choose the Task View lists as a good
place to start. ?If and when this number of packages becomes manageable, I
may add more.

I see, thanks for letting me know. Although not as reliable as the
Task Views, could the Crantastic popularity contest [1] be used for
this purpose?
