Visualize a Term-Document Matrix

Visualize correlations between terms of a term-document matrix.

Usage

"plot"(x, terms = sample(Terms(x), 20), corThreshold = 0.7, weighting = FALSE, attrs = list(graph = list(rankdir = "BT"), node = list(shape = "rectangle", fixedsize = FALSE)), ...)

Arguments

x: A term-document matrix.
terms: Terms to be plotted. Defaults to 20 randomly chosen terms of the term-document matrix.
corThreshold: Do not plot correlations below this threshold. Defaults to 0.7.
weighting: Define whether the line width corresponds to the correlation.
attrs: Argument passed to the plot method for class graphNEL.
...: Other arguments passed to the graphNEL plot method.

Details

Visualization requires that package Rgraphviz is available.

Examples

## Not run: data(crude)
# tdm <- TermDocumentMatrix(crude,
#                           control = list(removePunctuation = TRUE,
#                                          removeNumbers = TRUE,
#                                          stopwords = TRUE))
# plot(tdm, corThreshold = 0.2, weighting = TRUE)## End(Not run)
