MakeWordCloud: Plot a word cloud

In mobilizingcs/MobilizePrime: Simple functions for Mobilize

Description

Creates a word cloud from text that has been initialized to work as text in R. Defaults to plotting top 100 most often occuring words.

Usage

MakeWordCloud(text, color="BuGn", min.freq=2, top=100, format = 'count')

Arguments

text	a text object that has been initialized using the InitializeText function.
color	a color brewer specification for a color range. Defaults to "BuGn", but other options can be found using the command display.brewer.all(type="seq").
min.freq	the minimum frequency of words you want to appear in the word cloud. Default is 2, so only words that appear 2 or more times in your text will be displayed in the word cloud. You could change this to any other number that you wanted to be the minimum frequency. If you wanted all words that appeared, use 1.
top	an integer greater than 0 for format type 'count' or an integer greater than 0 and less than or equal to 100 for format type 'percent'. Determines the number of words, for 'count', or the percent of words, for 'percent', to plot.
format	must either be specified as 'count' or 'percent'. Use with the 'top' argument to determine how many words to plot.
