Installing R in Hadoop Cluster

There are multiple ways to install R & R studio in your unix system here I have described the simplest of them all by which I have been able to install R successfully in my system.

Installing R :-
Step1:- Download the latest R package from Cran.

Step2:- Choose a directory to install the R tree (R is not just a binary, but has additional data sets, help files, font metrics etc). Let us call this place R_HOME. Untar the source code. This should create directories src, doc, and several more under a top-level directory: change to that top-level directory.
Issue the following commands:

./configure
make

Step3:- Then check the built system works correctly by

make check

or

make check-devel

or

make check-all

Step4:- Then type

make install

This will install to the following directories:

prefix/bin or bindir

the front-end shell script and other scripts and executables

prefix/man/man1 or mandir/man1

the man page

prefix/LIBnn/R or libdir/R

all the rest (libraries, on-line help system, …). Here LIBnn is usually ‘lib’, but may be ‘lib64’ on some 64-bit Linux systems. This is known as the R home directory.

where prefix is determined during configuration (typically /usr/local) and can be set by running configure with the option --prefix, as in

./configure --prefix=/where/you/want/R/to/go

This causes make install to install the R script to /where/you/want/R/to/go/bin, and so on. The prefix of the installation directories can be seen in the status message that is displayed at the end of configure. The installation may need to be done by the owner of prefix, often a root account.
You can install into another directory tree by using

make prefix=/path/to/here install

Well that's it. This will complete the installation of R and now you can type R on your command prompt to get into R.

Installing R Studio[Cent OS] :-
