Hi,
I would like to create a custom key for a lattice xyplot in which line
elements are displayed on top of rectangle elements. In the example code
below, the lines and rectangles are shown side by side (the legend
itself is meaningless, but that is not the point). Is there a way to
overlay these key elements (but not the text)?
Thanks
xyplot(Sepal.Length + Sepal.Width ~ Petal.Length + Petal.Width,
iris,
type = c("p", "r"),
jitter.x = TRUE,
jitter.y = TRUE,
factor = 5,
key = list(
column=4,
text=list(lab=letters[1:4]),
lines=list(col=1:4, pch=1:4, type='b'),
rectangles=list(col=1:4, alpha=0.25, border=FALSE)
)
)
