This function implements wordcloud that compares documents. Code is adopted
from wordcloud::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, ... )
| x | a dfm or 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 |
| color | color of words from least to most frequent |
| font | font-family of words and labels. Use default font if |
| 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 |
| random_color | choose colors randomly from the colors. If |
| ordered_color | if |
| labelcolor | color of group labels. Only used when |
| labelsize | size of group labels. Only used when |
| labeloffset | position of group labels. Only used when
|
| fixed_aspect | logical; if |
| scale | deprecated argument |
| min.freq | deprecated argument |
| max.words | deprecated argument |
| random.order | deprecated argument |
| rot.per | deprecated argument |
| use.r.layout | deprecated argument |

| ... | additional parameters. Only used to make it compatible with wordcloud |
