How Install R on CentOS 7
{{postValue.id}}
To install R/R Studio on CentOS 7
R is a free programming language which is an implementation of S programming language on which it is compatible. R programming language is mostly used for statistics and data science by the data miners. In this tutorial we are going to see about the technique to install R programming language on CentOS 7
Installing R Studio
Before installing the R language, you need to install the epel-repository which is essential for the installation of R.

Log in with your non-root Linux user that you have created. After logging in, you would get to IDE as the following image.
Adding packages from CRAN
On above picture we see the R prompt where you can type commands. This commands will execute as non-root user. When you want to add new packages from CRAN (Comprehensive R Archive Network) you generally need to use root user. That way you will have packages usable for all users, while when adding as non-root, you will be able to use it only as that user. You can add packages as root outside of IDE, type sudo -i R on your server bash shell logged in as user. As we are going to add packages that are not entirely written in R, we need to add build tools first.

Making the Statistical graph in R-Studio
Let us make a statistical graph using R-Studio. Here we are going to make a graph of Hat stock. So, load the library you are going to use as follows.
library(' quantmod' )
Loading required package: xts
Loading required package: zoo
Attaching package: ‘ zoo’
The following objects are masked from ‘ package:base’ :
as.Date, as.Date.numeric

Version 0.4-0 included new data defaults. See ?getSymbols.
Add environment variable
> data < - new.env()
And plot data
getSymbols(' RHT' ,data)
As of 0.4-0, ‘ getSymbols’ uses env=parent.frame() and
auto.assign=TRUE by default.
This behavior will be phased out in 0.5-0 when the call will
default to use auto.assign=FALSE. getOption(" getSymbols.env" ) and
getOptions(" getSymbols.auto.assign" ) are now checked for alternate defaults
This message is shown once per session and may be disabled by setting
options(" getSymbols.warning4.0" =FALSE). See ?getSymbols for more details.
