You need to convert the axis units to the plot coordinate units - which is
happening in the background anyway for your plot. I'm not quite sure how to
explain this better past look again critically at the line below

as I suspect what you want to find the x value in something like
as.numeric(min(date values)) - the y value should be a little easier to work
out in this case. Again, I can only suggest use the locator() function to help
get a feeling for what the conversions have been if you are totally lost.
As a final thought, you will probably find a lot more help on such a topic as
generic plotting layout on the R-help list, not the geostatistics special
interest group. Or try the Murrell book "R Graphics"
