Quantitatively analyzes of D15 color panel tests
Description
D15Foutch Calculates angle, magnitude and scatter for VK-S 88 and VK-S 93 (Vingrys, A.J. and King-Smith, P.E. (1988, 1993)), LSA 05 (Foutch/Bassi '05), and JMO 11 (Foutch/Stringham/Vengu '11).
Usage
D15Foutch(userD15values=NULL, testType = 'D-15', dataVKS = NA)
Arguments

position values chosen by tester |
testType |
the CVD test to be scored: "D-15", "D-15DS", "Roth28-Hue" or "FM1OO-Hue" |
dataVKS |
by default, the original 1976 CIE Luv data from Vingrys and King-Smith |
Value
outmat |
data.frame with columns "angle", "magnitude" and "scatter" and rows "LSA05","JMO11","VKS88","VKS93" |
