Thanks for the reply. I looked at this before as I saw you had posted this, but this either doesn't work in my situation, or I am using it wrong.
Take the example in the function: tmp <- barplot(1:4) updateusr(tmp[1:2], 0:1, 1:2, 0:1) lines(1:4, c(1,3,2,2), lwd=3, type='b',col='red') But I want to use par(new=T) and plot(), so: tmp <- barplot(1:4) par(new=T) updateusr(tmp[1:2], 0:1, 1:2, 0:1) plot(1:4, c(1,3,2,2), lwd=3, type='b',col='red') The reason I do this is that the y-axis then corresponds to my plot() data. In my specific case, it's more like this: tmp <- barplot(c(1.5,40),yaxt='n',names.arg=1:2,ylim=c(0,1.25*40)) axis(4) par(new=T) updateusr(tmp[1:2], 1:2) plot(1:2,c(0.01,0.02),xaxt='n',pch=16) I want those points in the middle of the bars... but I want to keep the y-axis labels from the second plot. the par(new=T) probably wipes out the coordinates, so I'm not sure how use this?
