So many datasets remain unexplored, sometimes forever waiting to be analyzed even by simple exploratory and descriptive data analysis. Conclusions Being free of cost, it is surely a boon for researchers in developing countries and resource scarce institutions The quality of this software in terms of handling large datasets, having hundreds of functions with ever increasing number of add on packages and the neat outputs is also an advantage.
