Dear all
I have two questions regarding trellis plots - which I hope you may be able to
help me with.
Is it possible to place the key in a trellis plot on the panel (instead of
beside the panel)? This will cause the same key to be reproduced on each panel.
Please see the plot below - here I placed the legend below the plot. I tried
moving the key to the function statement, but it did not really work out the
way I expected.
One last thing, in the plot below I placed a horizontal line on the plot, is it
possible to only have the horizontal line on the left panel (I remember that in
S it was possible to state something like "if(get("cell",fr=9)==2)" in the
function statement to include the line on only one of the panels)?
All suggestions will highly appreciated.
