| plot {tm} | R Documentation |
Visualize correlations between terms of a term-document matrix.
## S3 method for class 'TermDocumentMatrix':
plot(x,
terms = sample(Terms(x), 20),
corThreshold = 0.7,
weighting = FALSE,
attrs = list(graph = list(rankdir = "BT"),
node = list(shape = "rectangle",
fixedsize = FALSE)),
...)
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. |
Visualization requires that package Rgraphviz is available.

data(crude)
tdm <- TermDocumentMatrix(crude)
set.seed(1234)
