Dear R People: Someone had asked about plotting 2 time series with the same time component with different scales(y axes). I had forgotten to save the question, but here is the answer:> data(USeconomic) > help(USeconomic) > plot(M1) > par(new=TRUE) > plot(GNP,axes=F,xlab="",ylab="") > axis(4) >Hope this helps!
