In hadley/ggplot1: Before there was ggplot2

Scale: categorical colour Create a scale for categorical colours.

Description

Continuous variables will automatically be converted to categorical using chop_auto. You may want to use chop to convert the values yourself for finer control.

Usage

sccolour(plot, name = "", h = c(0, 360), l = 65, c = 100, alpha = 1)

sccolor(plot, name = "", h = c(0, 360), l = 65, c = 100, alpha = 1)

scfill(plot, name = "", h = c(0, 360), l = 75, c = 100, alpha = 1)

Arguments

plot	ggplot object
name	name of the scale (used in the legend)
h	range of hues to use
l	luminance value
c	chroma value
alpha	alpha value

Details

This scale is automatically added when you have colour in your list of aesthetics. For finer control, you will need to set the scale yourself. See the example for some ideas.

Examples

p <- ggplot(reshape::tips, aes = list(x = day, y = tip))
ggjitter(p)
ggjitter(p, list(colour=sex))
ggjitter(p, list(colour=chop(tip, 3)))
sccolour(ggjitter(p, list(colour=chop(tip, 3))), l = 40)
