[R] Positioning text in top left corner of plot

[Greg Snow]

You can call par('usr') to find the current coordinates, then use the
text function (the pos and offset arguments may be helpful as well)

The cnvrt.coords function from the TeachingDemos package may also be of
help for finding coordinates for the text function.

Hope this helps,
