==== Installation of R packages in the user home ====

Users can have their own R packages installed. The following steps have to be done:

  - Create a .Renviron file, using 'vi' e.g.:<code>
vi ${HOME}/.Renviron 
</code>The content of this file points to the directory of your personal libraries, e.g.:<code>
R_LIBS=${HOME}/R/lib
</code>
  - create the directory, which was specified in .Renviron: <code>
mkdir -p ${HOME}/R/lib </code>
  - start R and install packages: <code>
install.packages('sp')
</code>
