FunctionReporter {pkgnet}

Function Interdependency Reporter

Description

This reporter looks at the network of interdependencies of its defined functions. Measures of centrality from graph theory can indicate which function is most important to a package. Combined with unit test coverage information—also provided by this reporter— it can be used as a powerful tool to prioritize test writing.

Details

R6 Method Support:

R6 classes are supported, with their methods treated as functions by the reporter.

• R6 methods will be named like <classname>$<methodtype>$<methodname>, e.g., FunctionReporter$private_methods$extract_nodes.

• Note that the class name used will be the name of the generator object in the package's namespace.

• The classname attribute of the class is not used. In general, it is not required to be defined or the same as the generator object name. This attribute is used primarily for S3 dispatch.

Known Limitations:

• Using non-standard evaluation to refer to things (e.g, dataframe column names) that have the same name as a function will trick FunctionReporter into thinking the function was called. This can be avoided if you don't use reuse function names for other purposes.

• Functions stored as list items and not assigned to the package namespace will be invisible to FunctionReporter.

• Calls to methods of instantiated R6 or reference objects will not be recognized. We don't have a reliable way of identifying instantiated objects, or identifying their class.

• Reference class methods are not yet supported. They will not be identified as nodes by FunctionReporter.
