This question was on the R-help mailing list today:
I have a data frame “test”:
test rep(7,length.out=length(test$total))
[1] 7 7 7 7 7 7 7 7

I highly recommend you [...]
Found on stackoverflow.com. I didn’t know about this way to make R automatically generate filenames for a series of plots:
jpeg(“~/tmp/rplots/foo%02d.jpg”)
for (i in 1:5) {
plot(i,ylim=c(0,6))
}
dev.off()
I’m actually not sure whether R does this, or the Linux shell.
