Well, maybe I don't get the problem, but you certainly have the
possibility to have two (or more) plots with the same axis without wasting
space in between (just like plot.mts() does for example).
Just set that margins to 0 and don't plot the x-axis but for the last
plot. For example you could do:
par(mar = c(0, 5.1, 0, 2.1), oma = c(6, 0, 5, 0), mfrow=c(2,1))
The layout then is very similar to that of plot.mts() as in:
plot(ts(cbind(rnorm(100), rnorm(100))), type = "p")
I hope this is what you wanted...
