 To run R code and visualize plots in Apache Zeppelin, you will need R on your master node (or your dev laptop).
 
-+ For Centos: yum install R R-devel
-+ For Ubuntu: apt-get install r-base r-cran-rserve
++ For Centos: `yum install R R-devel libcurl-devel openssl-devel`

 Validate your installation with a simple R command:
 
 ```
-R -e print(1+1)
+R -e "print(1+1)"
 ```
 
 Then install the required R libraries;
 
 + devtools with `R -e "install.packages('devtools', repos = 'http://cran.us.r-project.org')"`
