I've been struggling with this for a while and cannot get it to work.
Is there a simple way to add grid lines ---- I'd like to only add the
horizontal ones --- when using the groups argument in xyplot?
I can get the grid lines to plot, or the points/lines, but not both.
Here is a simple example of the sort of thing that I'm working with.
Thanks, in advance.
