I'm not seeing the result that you describe. Attached is the pdf that comes
from:
pdf(); print( 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)
)
) ); dev.off()
