[R] [EXTERNAL] Re: overlaying graphs in xYplot (Hmisc)

[Bert Gunter]

In lattice, e.g. xyplot, one simply uses panel functions to "overlay"
various constructs (point plots, smooth curves, text, etc.). If that
is relevant and you do not know about it, then you have homework to
do. ?xyplot or Deepayan's book or tutorials would be places to start
for that. Otherwise, ??.

I am trying to construct a graph using the xYplot() function in Hmisc package (thank you Frank Harrell) taking advantage of the Cbind() argument for plotting the median, 10th, and 90th quantiles and also the cbind() argument for individual data values.  I know how to do both of these separately, but I would really like to have them overlayed on each other.  I've tried various approaches with add=T, new=T, etc and none of those seem to work with xYplot().  Any pointers?
