Hello. I am having a problem directing the results of xYplot in the Hmisc package to a file. First I'll give you my sessionInfo and then my data and code, afterwhich I'll describe my problem.

When I try this with the trellis.device() the plot is only partially created. The axes are drawn but the actual plot area is empty except for the "curve" labels, although these are plotted on to of each other in the wrong place. I also tried putting my xYplot() inside a print() which gave the same results. -- Kevin E.
