Instead of trying to mix lattice and base functions, you might try using

maxtemp+mintemp ~ sampdate

David,
I certainly will. I've not needed R for projects for many months and when I
looked through previous scripts and the lattice book I failed to find what I
needed. So what I tried was a solution to a different but similar issue on
stackexchange.
Many thanks,
Rich
