scale_xaringan | R Documentation |
Color and fill single-color scales for discrete and continuous values,
created using the primary accent color of the xaringanthemer styles. See
vignette("ggplot2-themes")
for more information and examples of
xaringanthemer's ggplot2-related functions.

aes_type |
The type of aesthetic to which the scale is being applied. One of "color", "colour", or "fill". |

functions — one of |
color |
A color value, in hex, to override the default color. Otherwise, the primary color of the resulting scale is chosen from the xaringanthemer slide styles. |
direction |
Direction of the discrete scale. Use values less than 0 to
reverse the direction, e.g. |
inverse |
