polarLAB {colorspace} | R Documentation |
This function creates colors of class ``polarLAB''; a subclass of the virtual ``color'' class.
polarLAB(L, C, H, names)
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). |
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.
An object of class ``polarLAB'' which inherits from class ``color.''
