[R] Time Series Plots: Adding Custom Y-Axis Labels

[Rich Shepard]

   Working the examples in "Introductory Time Series with R" (pages 22-23).
When I use the plot command (e.g., plot(elect.decom <- decompose(elec.ts,
type = "mult")) the ylab command has no effect. Similarly, if I use xyplot.

   Is it possible to specify ylab values in time series plots? And what
strip.default() or strip.custom() options are needed to place specific
strings in the lattice xyplot strips? (I have read appropriate sections of
the Lattice book but have not found the proper syntax).
