terms_graph: terms_graph

In R.temis: Integrated Text Mining Solution

Description

Plot a graph of terms.

Usage

terms_graph(
  dtm,
  n = 100,
  min_occ = 0,
  interactive = base::interactive(),
  vertex.label.cex = 1,
  ...
)

Arguments

dtm	A DocumentTermMatrix object.
n	The maximum number of terms to represent.
min_occ	The minimum number of occurrences for a term to be retained.
interactive	If TRUE, show an interactive plot using tkplot. This is the case by default for interactive sessions.
vertex.label.cex	The font size for vertex labels. It is interpreted as a multiplication factor of some device-dependent base font size.
...	Optional arguments passed to plot.igraph or tkplot.

Value

The ID of the plot returned by tkplot if interactive=TRUE, or NULL invisibly otherwise.

Examples

file <- system.file("texts", "reut21578-factiva.xml", package="tm.plugin.factiva")
corpus <- import_corpus(file, "factiva", language="en")
dtm <- build_dtm(corpus)
terms_graph(dtm, 100, 3)
