This function impliments 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,

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
.
ajust sizes of words by a constant. Useful for non-Engish 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
