In srvanderplas/nppd: Functions for Analysis at Nebraska Public Power District

Description

Plot a cloud comparing the frequencies of words across documents.

Usage

comparison.cloud(term.matrix, scale = c(4, 0.5), max.words = 300,
  random.order = FALSE, rot.per = 0.1,
  colors = RColorBrewer::brewer.pal(6, "Dark2"), use.r.layout = FALSE,
  title.size = 3, ...)

Arguments

term.matrix	A term frequency matrix whose rows represent words and whose columns represent documents.
scale	A vector of length 2 indicating the range of the size of the words.
max.words	Maximum number of words to be plotted. least frequent terms dropped
random.order	plot words in random order. If false, they will be plotted in decreasing frequency
rot.per	proportion words with 90 degree rotation
colors	color words from least to most frequent
use.r.layout	if false, then c++ code is used for collision detection, otherwise R is used
title.size	Size of document titles
...	Additional parameters to be passed to text (and strheight, strwidth).
