Hello again

I'm trying to put error bars onto a barplot. I've tried something that 
Bill Simpson suggested a while ago, ie:

y<-c(1.1, 2.3, 3.0, 3.9, 5.1)
ucl<-c(1.3, 2.4, 3.5, 4.1, 5.3)
lcl<-c(.9, 1.8, 2.7, 3.8, 5.0)
plot(x,y, ylim=range(c(lcl,ucl)))

but I can't get it to work on a barplot. Any ideas?
