Hi,
If you want to export a single bar chart, this works:
png( "ET" );
barchart( data[,"ET"] )
dev.off()
quartz_off_screen

But if you want to export a few of them, this does not:
factorCols <- c("MR","ET");
sapply( factorCols, function(x) {
+ png( x );
+ barchart( data[, x] );
+ dev.off();
+ } );
MR.quartz_off_screen ET.quartz_off_screen

R gives no indication of an error, but the files do not appear in the
working directory as they should. Why is that?
I'm led to suspect this is a bug,
It much more likely to be related to the FAQ item (memory suggested it
was 7.21, but checking I see that I'm off by one) that discusses why
lattice functions won't plot as inexperienced useRs expect them to.

because it works fine if you use hist()
instead of barchart():
factorCols <- c("YR","AG");
sapply( factorCols, function(x) {
+ png( x );
+ hist( data[, x] );
+ dev.off();
+ } );
YR.quartz_off_screen AG.quartz_off_screen

Thanks,
Jeff
