Perhaps this:
Sz= c("h1","h2","h3","h4")
Pred=c(34790.0 ,47559.8, 21197.8, 28198.6)
Obs=c(34740 ,48615 ,20420, 26840)
plot(Pred, t="l", ylim=c(20000,50000))
text(Pred, Sz, cex=0.6, pos=4, col="red")
par(new=TRUE)
plot(Obs, t="l", ylim=c(20000,50000))
text(Obs, Sz, cex=0.6, pos=4, col="blue")
Alternatively you can use lines(), but always pay attention that both
graphs be constructed with teh same x and y limits.
