This function implements wordcloud that compares documents. Code is adopted
from comparison.cloud.
wordcloud_comparison(x, min_size, max_size, min_count, max_words, color,
font, adjust, rotation, random_order, random_color, ordered_color,
labelcolor, labelsize, labeloffset, fixed_aspect, colors, scale,
min.freq, max.words, random.order, rot.per, use.r.layout, title.size,
...)a dfm object
size of the smallest word
size of the largest word
words with frequency below min_count will not be plotted
maximum number of words to be plotted. least frequent terms dropped.
color of words from least to most frequent
font-family of words and labels. Use default font if NULL.
adjust sizes of words by a constant. Useful for non-English words for which R fails to obtain correct sizes.
proportion of words with 90 degree rotation
plot words in random order. If FALSE, they will be
plotted in decreasing frequency.
choose colors randomly from the colors. If FALSE,
the color is chosen based on the frequency
if TRUE, then colors are assigned to words in
order.
color of group labels. Only used when compariosn=TRUE.
size of group labels. Only used when compariosn=TRUE.
position of group labels. Only used when
comparison=TRUE.
if TRUE, the aspect ratio is fixed. Variable
aspect ratio only supported if rotation = 0.
