   The latest iteration, and the accompanying warning message:

xyplot(cbind(dalles.disch.ts, dalles.temp.ts), main = "Columbia River @ The
Dalles", xlab = "Date (Year.Month)", ylab = c("Temperature (C)","Discharge
(cfs)"), strip = FALSE, strip.left = strip.custom(par.strip.text =
trellis.par.get(c("Mean Temperature","Mean Discharge"))))

Warning message: In if (name %in% names(lattice.theme[[.Device]]))
lattice.theme[[.Device]][[name]] else NULL :
   the condition has length > 1 and only the first element will be used

   Please correct the syntax in the xyplot() function so the two strips have
the desired text.

Thanks,

Rich
