Hi,
I try to make a xyplot withou colors. I try:
pdf(file="test.pdf")
trellis.device(color=F)
Depth <- equal.count(quakes$depth, number=8, overlap=.1)
xyplot(lat ~ long | Depth, data = quakes)
dev.off()
the graphic is showed without colors in a X device but it dont work
saving directly on pdf device.
I'm not sure I know the correct answer, but report here the results of
my guesses:
Guess # 1 (completely wrong) was that the order of the first two lines
needed to be swapped.
Guess # 2. Look at ?pdf and see that there is a colormodel argument.
Partially successful but the points inside the panels and the edges of
the strip markers still show color.
Guess # 3: add col="black" to the xyplot call. Still leaves the orange
edges on the strip markers but is about 98% free of color.
Guess # 4: Remembering that the Lattice book website had different
color themes I went there to see if I could get code. Didn't work.
Then tried ?trellis.device and noted that htere is a device argument
as well as a color argument. This "works":
trellis.device(color=F, device="pdf")
pdf(file="test.pdf")
Depth <- equal.count(quakes$depth, number=8, overlap=.1)
xyplot(lat ~ long | Depth, data = quakes)
dev.off()
