[R] dotplot: labeling coordinates for each point

[Qifei Zhu]

Hi Deepayan,

Thanks for the hint. I spent some time on the research but haven't got any luck in writing the custom panel function for the conditional labeling of points in a graph. Could you please provide some more thoughts and probably some pseudo code? Thank you so much for your time!

Best,
Tony

Sure, write a panel function. See the examples in ?xyplot.
