levelplot

[Carlisle Thacker <thacker@aoml.noaa.gov>]

I have data in the form of a data frame with column x,y,z, where x,y
are evaluated a rectangular array.  However, x,y do not range over all
possible elements of the rectangular array.  When there data for most
of the elements, levelplot works as expected.  But when there are
relatively few elements with data, it doesn't; rectangles larger than
the array elements appear.

Any suggestions?
