Function gramcloud

Description

Plots wordcloud based on words and/or ngrams.

Usage

gramcloud(x = NULL, ngram = 1, max.num = 100, min.freq = 1,
  equal.shares = T, delete = T, lowerCase = T,
  main = "Cloud of n-grams", color = "red", random.order = FALSE,
  rot.per = 0.2, scale = c(4, 0.5), use.r.layout = T,
  ordered.colors = T, ...)

Arguments

x	Character vector containing the text of documents.
ngram	Numeric value that determines the maximum order of ngrams that is plotted. Defaults to 1.
max.num	Numeric value that determines the maximum number of ngrams plotted. Defaults to 100.
min.freq	Numeric value that determines the minimum number of occurences for a word or ngram to be plotted. Defaults to 1.
equal.shares	Logical value indicating whether the size of a word or ngram should be relative to all tokens of the same ngram-order (T) or corresponding to the least frequent constituting word or ngram (F). Defaults to T.
delete	Logical value indicating whether ngrams of lower order should be deleted if they are part of an ngram of higher order that is plotted. Defaults to T.
lowerCase	Logical value indicating whether x should be transformed to lower-case. Defaults to T.
color	Color of the most frequent ngram. Defaults to "red".
...	Additional graphical parameters for wordcloud.

Details

Plots wordcloud based on words and/or ngrams. By default words that are part of plotted ngrams are not plotted (delete=T).

Examples

gramcloud(c("This is an exemplary text","This is too","And this is probably the longest text"),ngram=2,min.freq=1)
