I think that plotting the spectral locus and the line of purples is trivial, but that's not actually what you are asking. Though filling in the interior with a color gradient would be a challenging and interesting problem, there are those who would consider this a misguided attempt at representation (even though it is frequently done) as the CIE coordinates provide no information on color appearance, per se. They specify what lights look alike, not what they look like. -- Kenneth Knoblauch Inserm U846 Stem-cell and Brain Research Institute Department of Integrative Neurosciences 18 avenue du Doyen Lépine 69500 Bron France tel: +33 (0)4 72 91 34 77 fax: +33 (0)4 72 91 34 61 portable: +33 (0)6 84 10 64 10 http://www.sbri.fr/members/kenneth-knoblauch.html ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
