R is an open source programming language and software environment for statistical computing and graphics that is supported by the R Foundation for Statistical Computing. [Wikipedia] Packages are the fundamental units of reproducible R code. They include reusable R functions, the documentation that describes how to use them, and sample data.
.Rprofile
.Rprofile file allows you to customize R for your environment. R looks for .Rprofile in your current working directory to source, on it's first try, and then checks in user's home directory. Some of the things that you can customize in .Rprofile are the following:
- .libPaths allows you to add a directory to it's library path, where you want to install R packages and use them.
.libPaths("~/R_LIBS")
- Following code allows you to hard code a mirror repo for CRAN.
r = getOption("repos") # hard code the UK repo for CRAN
r["CRAN"] = "http://cran.uk.r-project.org"
options(repos = r)
NOTE: Having .Rprofile in the user's home directory (~/.Rprofile), allows you to have a consistent setting throughout the cluster, and is generally advised.
Installation
Once you have setup .Rprofile to point to the directory where you want R to save and install your packages, load a module of R that you need.
[ravi89@c0113 ~]$ module load R/ R/2.15.3-goolf-1.7.20 R/3.3.1-intel-2016a-bare R/3.0.1-goolf-1.4.10-bare R/3.3.3-intel-2017a-X11-20170314 R/3.2.0-goolf-1.7.20 R/3.4.1-intel-2017a-X11-20170314 R/3.2.1-goolf-1.7.20 R/3.4.3-foss-2016b-X11-20160819 R/3.2.3-foss-2016a-bare R/3.5.0-foss-2018a-X11-20180131-bare R/3.2.3-intel-2016a-bare R/3.5.0-intel-2017a-X11-20170314-bare R/3.3.1-foss-2016b R/3.5.1-foss-2018a-X11-20180131-bare R/3.3.1-foss-2016b-no-X
After that start R, and use install.packages() to install the required packages.
[ravi89@c0023 ~]$ module load R/3.4.1-intel-2017a-X11-20170314
[ravi89@c0023 ~]$ R
R version 3.4.1 (2017-06-30) -- "Single Candle"
