Try this:
#some data
y1=rnorm(1:3)
y2=rnorm(1:3)
#draw two plots on the same screen
par(mfrow=c(2,1),oma = c(6, 0, 5, 0))
par(mar=c(0, 5.1, 0, 5.1))
plot(y1,xaxt="n",type="n") #1st plot
par(mar=c(0, 5.1, 0, 5.1))
plot(y2,xaxt="n",type="n") #2nd plot
#try to draw lines onto each plot on the screen
lines(y2) #draws a line in the 2nd plot
par(mfg=c(1, 1))
lines(y1,col=2) #also draws a line in the 2nd plot, but that's not what I
