Subject: plot legend outside the grid
Thanks for the pointers... I managed to get everything to look and feel the way
I want except for the legend to plot outside the grid... Thanks for the note on
the par, but I'm not able to it to plot outside the plot grid..

Of course!
stripchart() is a base graphics function and tehrefore has available to it
the base graphics functionality, like (the base graphics function, **not**
the lattice argument) legend(). See ?legend in the graphics package. Note
the use of locator() for positioning the legend.
Note: By default the legend will be clipped to the plot region. If you wish
to have a legend outside the plot region set the xpd parameter of par to
TRUE or NA prior to plotting.
