Usage
plotWordcloud(words, freq, rot.per = 0.3, max_min = c(1, 0.1), scale = 0.4, min.freq = 3, max.words = Inf, random.order = FALSE, colors = "black", random.colors = FALSE, fontface = 1, algorithm = "circle", tryfit = TRUE, add = FALSE, grob = FALSE, dimensions = unit(c(1, 1), "npc"))
Arguments
words
vector of words to draw
freq
frequencies for words, has to be the same length as words vector
rot.per
percentage of vertical words
max_min
relative scales to adjust the size difference between largest
and smallest word, by default the largest word is written with 10 times as
large font than the smallest
scale
a fraction of the available space on figure that will be
covered with the bounding boxes of words
min.freq
minimal frequency of words to be displayed
max.words
maximal number of words to be displayed
random.order
plot words in random order. If false, they will be
plotted in decreasing frequency
colors
vector of colors fro the words. This vector will be
extrapolated into as many colors as needed, starting with the first color
for lower frequencies and ending with last color for higher frequencies.
random.colors
if true, assigns random color for the words.
fontface
fontface for the words (1 - regular; 2 - Bold; 3 - italic)
algorithm
algorithm to find positions of words possible values:
"circle", "leftside" and "rightside".
tryfit
if TRUE the algorithm checks if all words fit to the figure,
if not it tries gradually smaller values of scale parameter until everything
fits
add
if TRUE adds the picture to existing plot.
grob
if TRUE returns the text grob instead of drawing it
dimensions
a two element vector of units giving the width and height
of the word cloud respectively
