I am doing a  xyplot: (x~y, groups = z, pch=8, auto.key=T). This changes
the symbol in the graph to an asterisk (*), but not in the legend, which
is still an open circle. I have found out how to manipulate the position
and the color of the letters in the legend, but cannot change the legend
symbol to match the symbol in the graph. Could you help?

 

Thanks,

Kaushik
