Hi,

 

I like to produce a series of levelplot graphs in postscript file, so I put
the trunk of codes including postscript() and levelplot() in a for loop. The
codes work fine outside the loop, but only produce empty .ps file when being
put within the loop. Is it a problem associated with postscript() or
levelplot()? How to get around the problem? Many thanks!
