The values can be provided in separate <code>X</code>, <code>Y</code> and <code>Z</code> vectors or in a three-column matrix passed as <code>X</code>.</p> </td></tr> <tr valign="top"><td><code>names</code></td> <td> <p>A vector of names for the colors (by default the row names of <code>X</code> are used).</p> </td></tr> </table> <h3>Details</h3> <p>The X, Y and Z values are the levels of the CIE primaries. These are scaled so that the luminance of the display white-point is 100. The white-point is taken to be D65, which means that its coordinates are 95.047, 100.000, 108.883. </p> <h3>Value</h3> <p>An object of class <code>XYZ</code> which inherits from class <code>color</code>. </p> <h3>Author(s)</h3> <p>Ross Ihaka </p> <h3>See Also</h3> <p><code><a href="RGB.html">RGB</a></code>, <code><a href="HSV.html">HSV</a></code>, <code><a href="LAB.html">LAB</a></code>, <code><a href="polarLAB.html">polarLAB</a></code>, <code><a href="LUV.html">LUV</a></code>, <code><a href="polarLUV.html">polarLUV</a></code>. </p> <h3>Examples</h3> <pre> ## Generate white in XYZ space XYZ(95.047, 100.000, 108.883) </pre> <hr /><div style="text-align: center;">[Package <em>colorspace</em> version 1.4-1 <a href="00Index.html">Index</a>]</div> </body></html>
