View source for Installing R packages locally



== Specifying a local library search location ==

Specify a local library search location.

You can use several library trees of add-on packages. The easiest way to tell R to use these via a 'dotfile' by creating the following file '$HOME/.Renviron' (watch the quotes and ~ character):
<pre>
  R_LIBS_USER="~/R/library"
</pre>
This specifies a keyword (<code>R_LIBS_USER</code>) which points to a colon-separated list of directories at which R library trees are rooted. You do not have to specify the default tree for R packages.

If necessary, create a place for your R libraries
<pre>
  mkdir ~/R ~/R/library         # Only need do this once
</pre>
Set your R library path
<pre>
  echo 'R_LIBS_USER="~/R/library"' >  $HOME/.Renviron
</pre>
== Installing to a local library search location ==

Start up R:

<pre>
  R                     # Invoke R
</pre>
Then, from the R environment, install the packages you require while pointing at the root R-package directory of choice. This example will install from CRAN.
<pre>
install.packages("name-of-your-package",lib="~/R/library")
</pre>
