Interactive 2-demensional density plots

Description

Creates an interactive plot using ggiraph. These functions extend gf_density2d(), gf_density_2d(), gf_density2d_filled(), and gf_density_2d_filled() with interactive features like tooltips and clickable elements.

Arguments

object	When chaining, this holds an object produced in the earlier portions of the chain. Most users can safely ignore this argument.
gformula	A formula with shape y ~ x. Faceting can be achieved by including | in the formula.

show.legend	Logical. Should this layer be included in the legends?
show.help	Logical. If TRUE, display some minimal help.
inherit	Logical. If TRUE, inherit aesthetics from previous layers.
environment	An environment in which to evaluate the formula.

A gg object that can be displayed with gf_girafe().

Additional interactive features

• onclick: JavaScript code (as character string) executed when clicking elements.

• Additional ggiraph aesthetics may be available depending on the geom.
