Thanks. ?That works well and it's simple.

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))
Just adding a type = "b" should work (for the lines), so something like: ?????? auto.key = list(space = "right", type = "b", ?????????????????????? points = FALSE, lines = TRUE) BTW, once you specify par.settings, you don't need to specify the parameters again, so you can drop the second line. Best, -Deepayan
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).
