Write a DOT language representation of an object for processing via Graphviz.
write_to_dot(x, con = stdout(), ...)
# S3 method for Weka_classifier
write_to_dot(x, con = stdout(), ...)
an R object.
a connection for writing the representation to.
additional arguments to be passed from or to methods.
Graphviz (https://www.graphviz.org) is open source graph
visualization software providing several main graph layout programs,
of which dot makes “hierarchical” or layered drawings of
directed graphs, and hence is typically most suitable for visualizing
classification trees.
Using dot, the representation in file foo.dot can be
transformed to PostScript or other displayable graphical formats using
(a variant of) dot -Tps foo.dot >foo.ps.
Some Weka classifiers (e.g., tree learners such as J48 and M5P)
implement a “Drawable” interface providing DOT representations
of the fitted models. For such classifiers, the write_to_dot
method writes the representation to the specified connection.
