This function creates colors of class “polarLUV”;
a subclass of the virtual “color” class.
Usage
polarLUV(L, C, H, names)
Arguments
L,C,H
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.
names
A vector of names for the colors (by default the row
names of L are used).
Details
The polarLUV space is a transformation of the CIE L*u*u*
space so that the u and u values are converted to polar
coordinates. The radial component C measures chroma and
the angular coordinate H is measures hue.
Value
An object of class “polarLUV” which inherits from class “color.”
