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):
R_LIBS_USER="~/R/library"
This specifies a keyword (R_LIBS_USER) 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
mkdir ~/R ~/R/library # Only need do this once
Set your R library path
echo 'R_LIBS_USER="~/R/library"' > $HOME/.Renviron
Installing to a local library search location
Start up R:
R # Invoke R
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.
install.packages("name-of-your-package",lib="~/R/library")
