subcolor_pal: Grouped color palette for factors

In eclarke/eclectic: Miscellaneous functions for bioinformatics data

Description

Picks a starting hue for each level of the factor, then returns colors with that hue, but varying luminosity for each item within that factor.

Usage

subcolor_pal(x, f, h = c(0, 360) + 15, c = 100, l = 65, l.range = 20,
  h.start = 0, direction = 1, na.value = "grey")

Arguments

x	the vector or factor grouped by f (i.e. Genus)
f	the vector or factor that groups the values of x (i.e. Order)
h	the range of hues to use
c	chroma value to use
l	the base luminance [0,100]
l.range	the luminance above and below the base to use for subcolors
h.start	the starting hue
direction	1=clockwise, 0=counterclockwise around color wheel

Value

a list containing 'major': the base color for each level in f; and 'minor': the color for each item in x
