[R] How to use "identify" --- Summary

[David Parkhurst]

I asked why my call to identify wasn’t working.  Thanks to Petr Pikal, 
Tom Mulholland, Gavin Simpson, and Duncan Murdoch for explaining that I 
had misinterpreted the ?identify help page, and that I needed to feed 
both the x and y vectors in the plot to identify().  It’s working fine 
for me now.
