Sorry, my first response was too hasty. Per the help file you need to use some
kind of interpolation method to resample whatever random data points you have
in a regular grid before you give it to contourplot.

thank you. yes, I got bitten by "FAQ 7.22: Why do lattice/trellis
graphics not work?" It had never occurred to me that this could be
expected behavior or a FAQ. (didn't show up in a google search for
contourplot.) Unless one knows, this is a puzzler. Thanks for the
pointer. so, a minimum work
The help for for contourplot answers this question in the description of the
formula (x) argument.

What does quartz() have to do with this? If quartz is the problem, R-sig-mac
would be a better place to ask. Or are you being bitten by R FAQ 7.22?

Dear R (3.2.0, osx) experts: I would like to create contourplots from
irregular data frames (i.e., not a matrix on a grid).I am getting
inconsistent results from lattice contourplot(). sometimes it works
(quartz plot on contours), sometimes it doesn't (blank plot = nada).
I have tried variati
