Regarding the S3 generic methods. My intention with the chart.Weights.EF<br>
function was that it would be a generic method for optimize.portfolio<br>
and efficient.frontier objects. Since chart.Weights is already a generic<br>
method for optimize.portfolio objects, I don't think chart.Weights can<br>
be used a generic function to chart weights along the efficient<br>
frontier. I think I should just rename chart.Weights.EF to chart.WeightsEF.<br>

Can the efficient.frontier opbjects be subclassed from the optimize.portfolio objects? (I haven't looked closely at the structure there, so I don't know)<span class="HOEnZb"><font color="#888888"><br>
