Arguments

x	a dfm or quanteda.textstats::textstat_keyness object
min_size	size of the smallest word
max_size	size of the largest word
min_count	words with frequency below min_count will not be plotted
max_words	maximum number of words to be plotted. The least frequent terms dropped. The maximum frequency will be split evenly across categories when comparison = TRUE.
color	colour of words from least to most frequent
font	font-family of words and labels. Use default font if NULL.
adjust	adjust sizes of words by a constant. Useful for non-English words for which R fails to obtain correct sizes.
rotation	proportion of words with 90 degree rotation
random_order	plot words in random order. If FALSE, they will be plotted in decreasing frequency.
random_color	choose colours randomly from the colours. If FALSE, the colour is chosen based on the frequency
ordered_color	if TRUE, then colours are assigned to words in order.
labelcolor	colour of group labels. Only used when comparison = TRUE.
labelsize	size of group labels. Only used when comparison = TRUE.
labeloffset	position of group labels. Only used when comparison = TRUE.
fixed_aspect	logical; if TRUE, the aspect ratio is fixed. Variable aspect ratio only supported if rotation = 0.
scale	deprecated argument
min.freq	deprecated argument
max.words	deprecated argument
random.order	deprecated argument
rot.per	deprecated argument
use.r.layout	deprecated argument
title.size	deprecated argument
...	additional parameters. Only used to make it compatible with wordcloud
