getDefaultAttrs {Rgraphviz} | R Documentation

## Functions to generate and check global attribute lists

### Description

The `getDefaultAttrs` function can be used to generate a default global attribute list for Graphviz. The `checkAttrs` function can be used to verify that such a list is valid for use.

### Usage

    getDefaultAttrs(curAttrs = list(), layoutType = "dot")
    checkAttrs(attrs)

### Arguments

`curAttrs` | Any attributes currently defined
`layoutType` | The layout method being used. Defaults to dot, and see `graphvizCapabilities()$layoutTypes` for possible values.
`attrs` | An attribute list of graphviz attributes

### Details

The `getDefaultAttrs` function generates a four element list (elements being “graph”, “cluster”, “node” and “edge”). Contained in each is another list where the element names correspond to attributes and the value is the value for that attribute. This list can be used to set global attributes in Graphviz, and the exact list returned by `getDefaultAttrs` represents the values that are used as basic defaults.

The `checkAttrs` function can be used to verify that a global attribute list is properly formed.
