User Installed Software - R/CRAN
Installing R/CRAN add-ons in your user account
R is a free software environment for statistical computing and graphics. There exists a large number of R add-on packages. HPC2N has only a few installed (see our main R page). If you need more than those, the quickest and sometimes best solution is to install those add-ons on your own account.
We need create a place for the add-ons to be and tell R where to find them. This needs only to be done once.
- Create a directory to store your add-ons in, here we choose $HOME/Public/R-packages:
mkdir -p $HOME/Public/R-packages
- R reads the $HOME/.Renviron file to setup its environment. But since you want to be able to use R from the batch system, we need to create a link into the Public directory:
ln -s $HOME/Public/.Renviron $HOME
- Since the file probably is empty now, tell R where your chosen add-on directory is with the command line:
echo R_LIBS=\"$HOME/Public/R-packages\" > ~/.Renviron
However if it is not empty, you can edit $HOME/.Renvion with your favorite editor so that R_LIBS contain the path to your chosen add-on directory. It should look something like this when you are done:
NOTE: Replace "/home/u/user" with the value of $HOME. Run 'echo $HOME' to see its value.
Installing R add-ons
There are two ways to install an R add-on from CRAN, which is not installed on our system. You can either choose the one that automatically downloads the add-on and handles all the dependencies, or one that is somewhat simpler and does not handle dependencies.
Automatic download and install
- Load the R module first
- Tell R to install the plyr add-on from the CRAN repo in Sweden (chosen from CRAN mirror list). We ask R to be quiet and don't bother saving and restoring the environment.
R --quiet --no-save --no-restore -e "install.packages('plyr', repos='http://ftp.acc.umu.se/mirror/CRAN/')"
You get a warning about 'lib' being unspecified. You can safely ignore that.
If the package has dependencies that come from more than one repo it will not work. You either run the "install.packages" interactively in R or use method two.
Manual download and install
- Download the add-on of interest from the CRAN Package site. In this case we download http://cran.r-project.org/src/contrib/ash_1.0-9.tar.gz (it has no dependencies):
- Load the R module first
- Tell R to install it into your chosen add-on directory:
R CMD INSTALL -l $HOME/Public/R-packages ash.tar.gz
To use you installed add-ons, just use the following R expression to load the plyr add-on (replacing "plyr" with your add-on):
