I wonder if you noticed that you had managed to create a "fig"
object that has two "inside" lists by specifying first a key "list"
which required a legend list, and then specifying a "legend" list
that also had a key function? The solution to your specific request
by Kortschak "nulled-out" the second of those.
A rather confused reply, I am afraid. I misattributed Lugue's posting
to Kortschak. Lugeue obviously was aware of the structure of the fig
object, since he correctly addressed the problem he originally posed.

Hi,
I thought the following would only remove the legend element of a
trellis object, but it actually removes both the legend and key
elements:
---<--------------------cut here---------------
start------------------->---
fig <- xyplot(Sepal.Length ~ Petal.Length, groups=Species,
data=iris,
key=list(x=1, y=0.02, corner=c(1, 0), size=3, between=1,
text=list(levels(iris$Species))),
legend=list(inside=list(fun="draw.key", x=0, y=1,
corner=c(0, 1),
args=list(key=list(text=list("a)",
cex=1.5)),
draw=FALSE))))
update(fig, legend=NULL)
---<--------------------cut here---------------
end--------------------->---
Is this the right way to remove an element from the object, using
update.trellis()? Thanks.
It probably depends on the element. In the case of "key", it is a
descendant of the legend list so when you make legend NULL you are
wiping out all of its descendants as well:
> str(fig)
List of 43
snipped a few lines
$ legend :List of 2
..$ inside:List of 5
.. ..$ fun : chr "draw.key"
.. ..$ args :List of 2
