Packages
0.1 Wordclouds
0.1.1 Load Data
Before importing, you should save your file as UNICODE UTF-8 or else you need to replace fancy punctuation yourself (using select, search, replace with simple, or space). This is perhaps easiest to do in a generic text editor like Notepad. For example: * fancy quote marks (fancy “ ” or ’ ’) * fancy en and em dashes (fancy – or —) * fancy ellipsis (fancy …) * fancy list characters (bullet lists) * and anything else fancy Also, it is easiest to remove URL (web links) yourself. Also, file must end with a blank line.
0.1.2 Clean the text data
This file was imported after saving in Word as UNICODE UTF-8
0.1.3 Create Corpus
0.1.4 Create TDM (term-document-matrix)
TDM is a Table of counts
Some words end up being too long (too many letters). You can remove such words with smaller maxLength
You can change minimum number of times for a word to be included with minFreq
You can change the total number of words in the cloud with maxTerms
0.1.5 Optional: Stemming
0.2 Stats (Bar Chart, Other)
You can increase number of bars with maxBars (but 20 is a good max for bar chart)

- size = Font size, default is 1. The larger size means the bigger word.
- shape = Available presents are ‘circle’ (default), ‘cardioid’ (apple or heart shape curve, the most known polar equation), ‘diamond’ (alias of square), ‘triangle-forward’, ‘triangle’, ‘pentagon’, and ‘star’.
- ellipticity = degree of “flatness” of the shape wordcloud2.js should draw.
