I'm using xyplot in a very simple way---a scatter plot of several data
sets. I'm having a problem getting auto.key to display different
point characters.
The following produces a plot that employes different colors, all with
pch(1), for the different groups, with a matching key.
xyplot(Force~Time, rawData, groups=Sample, panel = panel.superpose,
auto.key=TRUE)
The following produces a plot that employs different symbols (and
colors) for the groups, but the key still uses pch(1) for all groups.
I assume I need to set some more general option, but haven't found it
yet.
xyplot(Force~Time, rawData, groups=Sample, pch=0:18, panel =
panel.superpose, auto.key=list(space="right", pch=0:18))
What I would really like is a plot with different symbols, all with
black color. The following works for the plot, but again has no
effect on the key.
xyplot(Force~Time, rawData, groups=Sample, pch=0:18, col="black",
panel = panel.superpose, auto.key=list(space="right", pch=0:18))
Try this:
xyplot(Sepal.Width ~ Petal.Width, data = iris, groups = Species,
par.settings = list(superpose.symbol = list(col = 1, pch = 0:2)),
auto.key = TRUE)
