Create a character vector of RGB values based on hue, saturation,
and lightness (HSL). This is a similar color space to HSV, but is
parameterized differently.
USAGE:
hsl(h=1, s=1, l=0.5, gamma=1, alpha=1)
OPTIONAL ARGUMENTS:
h
Hue specified as a numeric between 0 and 1. Single value or vector.
s
Saturation specified as a numeric between 0 and 1. Single value or vector.
l
Lightness specified as a numeric between 0 and 1. Single value or vector.
This is also called the luminance.
gamma
Gamma correction specified as a numeric between 0 and 1. Single value or vector.
alpha
Alpha specified as a numeric between 0 and 1. Single value or vector.
VALUE:
Character vector of RGB values such as
"#FF0000" if alpha is not
specified, or
"#FF000080" including alpha.
SIDE EFFECTS:
None.

EXAMPLES:
# Piechart with colors generated using hsl()
pie(rep(1, 16), col=hsl(h=seq(0.1, 0.9, length=16), s=0.75, l=0.6))
