Arguments

x

a dfm 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. least frequent terms dropped.

color

color 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 colors randomly from the colors. If FALSE, the color is chosen based on the frequency

ordered_color

if TRUE, then colors are assigned to words in order.

labelcolor

color of group labels. Only used when compariosn=TRUE.

labelsize

size of group labels. Only used when compariosn=TRUE.

labeloffset

position of group labels. Only used when comparison=TRUE.

fixed_aspect

if TRUE, the aspect ratio is fixed. Variable aspect ratio only supported if rotation = 0.
