About the Software
R is 'GNU S', a freely available language and environment for statistical computing and graphics which provides a wide variety of statistical and graphical techniques: linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, etc. Please consult the R project homepage for further information.
Usage
On Super Mike 2, R 3.2.0 was compiled by gcc 4.7.2. So make sure gcc 4.7.2 has been added into the user environment by softenv. If not, as the default gcc loaded is 4.4.6, following error messages when trying to use R 3.2.0 will appear:
$ R
WARNING: ignoring environment value of R_HOME
/usr/local/packages/R/3.2.0/gcc-4.7.2/lib64/R/bin/exec/R: error while loading shared libraries: libquadmath.so.0: cannot open shared object file: No such file or directory
and R will not run. So again please make sure gcc 4.7.2 has been loaded.
R may be run either interactively via the R console, or as a batch process reading commands from a script file.
To launch the R console, simply execute the R command. After the console is launched, users can run R commands at the prompt:
$ R

Rscript, on the other hand, can be used to run a R scirpt in which a sequence of R commands has been saved. The syntax is:
$ Rscript <options> <name of the R script>
For example:
$ cat hello.R
print("Hello World!")
$ Rscript hello.R
[1] "Hello World!"
