chart {struct} | R Documentation

## Constructor for struct chart objects

### Description

A base class in the struct package. Should not be called directly.

### Usage

    chart(...)

### Arguments

`...` | named slots and their values that get passed to struct_class

### Details

The `chart` class provides a template for figures, charts and plots associated with other objects. For example, a DatasetExperiment object could have a histogram plotted for a specified column.

Charts can have parameters but not outputs (other than the figure itself), as chart objects are not intended to be used for calculations. The `chart_plot` method can be used to display a chart for an object, and `chart_names` can be used to list all chart objects associated with an object.

Classes that inherit the `stato` class have STATO integration enabled, allowing stato_id to be set and formal names and descriptions pulled from the STATO ontology database.

### Value

a chart object

a struct_class object

### Examples

    C = example_chart()
