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)
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))
updateusr(tmp[1:2], 1:2)

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? 

Thanks Again.
