Word Cloud using Twitter Data (and Regular Expression) and Tidy Data Methodology

• A visualization technique for text data will be explored. We start with extracting data from Twitter and discuss how to clean up the text for analysis. New R users can learn the basics of regular expression. Once stop words are removed, a word cloud will be generated.

• We continue to work with the Calgary Police Crime Statistics. We will reformat the data according Hadley Wickham's "Tidy Data" methodology and add 2017 Calgary census data to the existing dataset, and perform some more exploratory data analysis.
