Hi,
I'm struggling to find if there is a simple way to make the lines and points
overlap in a legend for a lattice plot using auto.key. Here is a toy example
of what doesn't work (for me) as the lines and points are adjacent rather than
overlapping:
library(lattice)
d <- data.frame(x = 1:2, y = 1:4, f = factor(letters[1:2]))
xyplot(y ~ x, d, groups = f, type = "b",
pch = 21:22, fill = c("white", "black"), col = "black",
par.settings = list(superpose.symbol =
list(pch = 21:22, fill = c("white", "black"), col = "black"),
superpose.line = list(col = "black")),
auto.key = list(space = "right", points = TRUE, lines = TRUE))
I've seen a few examples on stack.overflow but I haven't been able to make them
work, or they seem more complicated then I would think it should be (but I
don't exclude that I'm fooling myself there).
