schcl: Scale: colour (hcl) Scale continuous variables to hue, chroma...

In hadley/ggplot1: Before there was ggplot2

Description

This colour map is the most perceptually uniform. However, use multiple mappings with care. It is often a good idea to restrict the range of the hue, as shown in the example.

Usage

schcl(plot, name = "", to = list())

scfillhcl(plot, name = "", to = list())

Arguments

plot	plot
name	namen of the scale (used in the legend)
to	named list of target ranges (r.to, g.to, b.to, a.to)

Details

Note: alpha mappings only work with the Quartz and PDF devices.

Examples

p <- schcl(ggplot(reshape::tips, aes = list(x = total_bill, y = 1)))
ggjitter(p, list(h = tip))
ggjitter(p, list(c = tip))
ggjitter(p, list(l = tip))
