Create interactive repulsive textual annotations

The geometries are based on ggrepel::geom_text_repel() and ggrepel::geom_label_repel(). See the documentation for those functions for more details.

Usage

geom_text_repel_interactive(...)

geom_label_repel_interactive(...)

Arguments

...

arguments passed to base function, plus any of the interactive_parameters.

Note

The ggrepel package is required for these geometries

Details for interactive geom functions

The interactive parameters can be supplied with two ways:

• As aesthetics with the mapping argument (via ggplot2::aes()). In this way they can be mapped to data columns and apply to a set of geometries.

• As plain arguments into the geom_*_interactive function. In this way they can be set to a scalar value.
