How to create side by side barplot in base R?

If we want to create side by side barplot for two vectors or two columns of same or different data frames then we first need to combine those vectors or columns with the help of cbind function as shown below. After that barplot function will be applied to the combined data and beside argument will be set to TRUE.

Check out the below given example to understand how it works.
