[R] multiple lines on multiple plots

I'm sure this must be trivial, but I'm a novice with R and can't work out how to handle the axes when I am constructing multiple plots on a page and try to return to a previous one to put multiple data sets it.

A simple example:

x<- 1:10
y<- (1:100)*3


The first 5 lines make two plots with a row of dots along the diagonal of each. I intended the last two statements to add a line to the first plot, that runs along the same data points already plotted there. However, although the commands add a line to the top plot, it is clearly using the axis dimensions of the lower plot. Can someone tell me how to get it to use the axes that are already there?

Variants like lines(x,xlim=c(1,10)) have no effect.

Thanks in advance for any help.
