-## install R packages
+- install R packages
 
 Here is a simple code to install all the necessary R packages to keep you up and running. The script will check whether the required packages have been installed, if not, it will install them accordingly.
 
 > install <- function(packages){
+>  
 >   new.packages <- packages[!(packages %in% installed.packages()[, "Package"])]
+>  
 >   if (length(new.packages)) 
+>  
 >     install.packages(new.packages, dependencies = TRUE)
+>  
 >   sapply(packages, require, character.only = TRUE)
+>  
 > }
 >  
+>  
 > required.packages <- c("package1", "package2" )
+>
 > install(required.packages)
