Ken, I followed your suggestion and perhaps I don't understand what to expect
from convertColor or maybe I'm not using it correctly. Consider the following
tests:

X - D65[1]*D65[3]/D65[2] # conversion per brucelindbloom.com
Y -
You seem to treating the input values as xyY when they should be XYZ
(case matters).
So, I would do something like this
D65 - c(0.3127, 0.329, 0.3583)
X - 100 * D65[1]
Y - 100 * D65[2]
Z - 100 * D65[3]
XYZ - data.frame(X = X, Y = Y, Z = Z)
convertColor(XYZ, from = XYZ, to = sRGB)

Thank you Ken.
90% of my problem was missing the factor of 100. I was just inputing xyY as a
test, I wasn't sure whether the docs were being clear about nomenclature.
