RMH> To match the barplot scaling, you need to do a lienar transformation.

With your idea, the following code gives to me what I want:

z_data.frame(size=c(3720,16962,11627,9676),mean=c(.6,.7,.3,.5),ax=0:3)
z
tmp_barplot(z$size,names=as.character(z$ax))
par(new=T)
plot(tmp,z$mean,type="l",ylim=c(.3,.8),xlab="Age",ylab="",axes=F,xaxs='d')
