plot with two y axes
I'm trying to make a transition from S-plus under Windows to R under
Linux. My immediate aim is to produce a scatter plot with two y-axes
with different scales. That can be done in S-plus with a command of the
following form:
guiPlot( PlotType="Scatter", DataSet="execon",
Columns="years,hstart,ship", AxisType="Multiple Y" ),
where years, hstart, and
