[R] how to represent error bar in a plot legend?

[John Kane]

Can you give us a working example of what you are doing?
I don't understand why you would need a pch symbol for an error bar.
 
Perhaps if you are using an unboxed legend you could just use arrow() and text() to add the error bar to the legend?
