Plotting two time series

["Data Analytics Corp." <dataanalytics@earthlink.net>]

Hi,

I have a matrix with two time series, the S&P500 and the Consumer 
Confidence Index, created using the function timeSeries().  Let's say I 
create
x <- timeSeries(data, from = timeCalendar(d=1, m=1, y = 2004))

I can easily plot one of the components using

plot.timeSeries(x$sp500).  Similarly for, say, confidence.  The series 
x$sp500 and x$confidence have different scales.  I'd like to have them 
on one plot with the scale for the S&P500 on the left and the scale for 
the Confidence Index on the right    If I use
plot.timeSeries(x)

then both are drawn on the same plot area, but the scales are not for 
the series individually so the graph is hard to read.  I can do this in 
Stata (with a little effort) but I'd prefer to do it in S+.  How can 
this be done?  Any suggestions?
I'm using S+8 on Windows Vista.

Thanks,

Walt Paczkowski
