R help - Sep 2010 - xyplot legends

Hi all, I

When I plot both lines and points using type=c('l', 'p') in
xyplot(), if I want
to include in legend both of them using keys=list(lines=list(col=1:3), 
points=list(pch=1:3)), the lines and points are plotted side by side in legend. 
Is there anyway to plot the points in the middle of the lines instead? 


that is the default is plotting like this:
----- o

but I want something like this:
---o---

Thanks for any suggestions

John

It's "key", not "keys"

See if this is closer to what you had in mind:

key=list(type="o", lines=list(col=1:3,pch=1:3, size=4 )

The best I could do was:
  -o--o--o-
