polarLAB.Rd
This function creates colors of class ``polarLAB''; a subclass of the
virtual color-class
class.
polarLAB(L, C, H, names)
these arguments give the L, C and H coordinates of the colors.
The values can be provided in separate L
, C
and H
vectors or in a three-column matrix passed as L
.
A vector of names for the colors (by default the row names of
L
are used).
An object of class polarLAB
which inherits from class color
.
The polarLAB space is a transformation of the CIE L∗a∗b∗ space so that the a and b values are converted to polar coordinates. The radial component C measures chroma and the angular coordinate H is measures hue.
