D15Foutch: Quantitatively analyzes of D15 color panel tests

In CVD: Color Vision Deficiencies

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

userD15values	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"
