 TIDY DATA HADLEY PAPER
 Package ‘tidyr’: tidyr is an evolution of reshape2. It's design specifically for data tidying (not general reshaping or aggregating) and works well with dplyr data pipelines.

 Package ‘stringr’: stringr is a set of simple wrappers that make R's string functions more consistent, simpler and easier to use.
 Package ‘stringdist’: Implements an approximate string matching version of R's native 'match' function. Can calculate various string distances based on edits (dameraulevenshtein, hamming, levenshtein, optimal sting alignment), qgrams or heuristic metrics
 Package ‘FSelector’: This package provides functions for selecting attributes from a given dataset
