With these functions the user can add interactivity to various theme elements.

They are based on element_rect(), element_line() and element_text() See the documentation for those functions for more details.

element_line_interactive(...)

element_rect_interactive(...)

element_text_interactive(...)

Arguments

...

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

Details for element_*_interactive functions

The interactive parameters can be supplied as arguments in the relevant function and they should be scalar values.

For theme text elements (element_text_interactive()), the interactive parameters can also be supplied while setting a label value, via the labs() family of functions or when setting a scale/guide title or key label. Instead of setting a character value for the element, function label_interactive() can be used to define interactive parameters to go along with the label. When the parameters are supplied that way, they override the default values that are set at the theme via element_text_interactive() or via the guide's theme parameters.
