I know how you feel,
I came a cross the same problem once, which took sometime to find a
solution
for.
What you need to do is put the hist into a variable and then plot
it, for
example:
library(lattice)
for(i in 8:153){
hist.to.plot <- histogram(~ data[,i] | data[,2],
data
=
data
,,ylab
=
"Frequency
",xlim=c(1,5),xlab="Score",ylim=c(0,100)),main=paste(colnames(data)
[i],sep="")
plot(hist.to.plot)
}
Cheers,
Tal

And I also want to save each histogram in each separate pdf
file using
the
following codes ?.
png("hist.png[i]")
dev.off()
Try png(paste("hist",i,".png",sep="") instead.
