Extract plot components from a ggplot or gtable. get_plot_component() extracts grobs or a list of grobs. plot_component_names() provides the names of the components in the plot. plot_components() returns all components as a list.

get_plot_component(plot, pattern, return_all = FALSE)

plot_component_names(plot)

plot_components(plot)

Arguments

plot

A ggplot or gtable to extract from.

pattern

The name of the component.

If there is more than one component, should all be returned as a list? Default is FALSE.

Value

A grob or list of grobs (get_plot_component(), plot_components()) or a character vector (plot_component_names())

Examples

library(ggplot2) p <- ggplot(mpg, aes(displ, cty)) + geom_point() ggdraw(get_plot_component(p, "ylab-l"))
