legend doesn't render colors/styles passed via poly.args/ellipse.args/hull.args #40
Description
As of version 1.0-5, legends will correctly render colors, linewidths, and line types specified through the ordinary graphical parameters col, lwd, and lty when passed as part of the main plotVowels call. However, although passing color and style information through the named lists poly.args, ellipse.args and hull.args works for controlling the color and style of polygons, ellipses, and hulls (respectively), the code that creates the legend currently does not pick up that color and style information.
