FW: Trellis (unwanted line)

["Keenan, Sean" <sean.keenan@citi.com>]

> Dear Group;
> I am using S-Plu 2000 Pofessional Release 1.  To consider the potential
> importance of a variable left out of a regression (OPMAR is the variable),
> I seek to plot it against some residuals grouping by industry (11 groups)
> by issuing the command:
> xyplot(d$residuals~mod$OPMAR|mod$IND).
> This is fine, but it gives me un unwanted axis line halfway through the
> rightmost column of panels.  Why does it do this and how can I make it
> stop?
> Thanks,
> Sean Keenan
