Easily add legend title(s)

Description

Update the title(s) of the specified aesthetic, or all aesthetics at once.

Usage

easy_add_legend_title(..., teach = FALSE)

Arguments

...

A list of new name-value pairs. The name should be an aesthetic. If only a character value is provided then all legend titles will be changed to that.

teach

Value

a theme object
