graphvizVersion {Rgraphviz} | R Documentation

## A function to determine graphviz library version

### Description

This function will query the graphviz libraries that the package was built against and report what version of Graphviz is being used.

### Usage

    graphvizVersion()

### Value

A list with three elements, two of class `numeric_version`. The first element named `installed_version` represents the version of Graphviz that is being used by the package. The second element named `build_version` represents the version of Graphviz that was used to build the package. A mismatch between these two versions may indicate problems. The third element is a logical named `bundled_graphviz` and indicates if Rgraphviz is using the bundled Graphviz (default) or an external Graphviz.
