dot {RWeka} | R Documentation

## Create DOT Representations

### Description

Write a DOT language representation of an object for processing via Graphviz.

### Usage

    write_to_dot(x, con = stdout(), ...)
    ## S3 method for class 'Weka_classifier':
    write_to_dot(x, con = stdout(), ...)

### Arguments

`x` | an R object.
`con` | a connection for writing the representation to.
`...` | additional arguments to be passed from or to methods.

### Details

Graphviz (http://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.
