ggplot2 scales from an MLB team palette

Colour and fill scales that take their colors from an MLB team, the ggplot2 counterpart of mlb.colors. scale_color_mlb is an alias for scale_colour_mlb.

Usage

scale_colour_mlb(set, discrete = TRUE, reverse = FALSE, legacy = FALSE, ...)

scale_color_mlb(set, discrete = TRUE, reverse = FALSE, legacy = FALSE, ...)

scale_fill_mlb(set, discrete = TRUE, reverse = FALSE, legacy = FALSE, ...)

Arguments

set

Character string naming an MLB team. See colorr.teams("mlb").

discrete

Logical. TRUE (the default) builds a discrete scale; FALSE builds a continuous gradient through the team's colors.

reverse

Logical. If TRUE, reverse the color order.

legacy

Logical. If TRUE, use the palette that shipped with colorr 1.0.1.

...

Passed on to discrete_scale when discrete is TRUE, otherwise to scale_fill_gradientn or scale_colour_gradientn.

Value

A ggplot2 scale, to be added to a plot with +.
