Many thanks to Andrew Bruce and Steve McKinney for showing me how to look at
?class.timeDate. I have a plotting question this time for the postwar
quarterly real GDP series. A common plot in macro economics is a plot of
real GDP with shading bars showing the dates of recessions (peak to trough).
Can such a graph be done using the Splus plotting functions? I have seen
shading done on the intraday plots created by plot and trellisPlot.
