Yes, and I agree that in principle it would be a good thing to have.
Personally, I don't believe such a theme can be made (at least not one
that's generally useful) and will not spend time trying to create one.
I'm happy to add one to lattice if anyone contributes it.

Here is an example of 'in between':
--8<---cut here---start->8---
## Set background color of strips to grayscales:
strip.background <- trellis.par.get("strip.background")
trellis.par.set(strip.background = list(col = grey(7:1/8)))
## Set color of plot symbols to grayscale:
plot.symbol <- trellis.par.get("plot.symbol")
trellis.par.set(plot.symbol = list(col = grey(5/8)))
--8<---cut here---end--->8---
I think it would be nice to have a few default "themes": A single
switch between "default color", "grayscale" and "black and white".
What do you think?
Cheers,
Patrick

Goal:
Lattice should have good default settings for color, grayscale and
b&w.
The user should not be bothered with the details (similar to using
LaTeX: Many users do not have any idea of DEK's typesetting in the
background).
Lattice functions should provide reasonable default settings.
The default colors for the lattice suite were chosen for a reason
(very good choice for color display).
IMO the default grayscale colors should be wrapped into a similar
default-suite after discussion of which grayscales are best suited for
printing with different common resolutions using b/w printers.
After this has been decided upon, it might be nice to have something
along the lines of:
lattice.options(default.theme = [color|gray|bw])
Have I described my concern elaborately enough?

This looks very interesting, thanks for keeping the development going!

Well, there you go. You have a new theme.

I'm still not sure what qualities you are looking for in the new
theme. An upcoming version of the latticeExtra package will have a
function that can be used to create a theme based on some given
colors; you might find it useful. It uses colors from RColorBrewer by
default, and looks like:
brewer.theme <-
function(symbol = brewer.pal(n = 8, name = "Dark2"),
fill = brewer.pal(n = 12, name = "Set3"),
region = brewer.pal(n = 11, name = "Spectral"),
reference = "#e8e8e8",
bg = "transparent",
fg = "black")
{
theme <-
list(plot.polygon = list(col = fill[1], border = fg[1]),
box.rectangle = list(col= symbol[1]),
box.umbrella = list(col= symbol[1]),
dot.line = list(col = reference),
dot.symbol= list(col = symbol[1]),
plot.line = list(col = symbol[1]),
plot.symbol = list(col= symbol[1]),
regions = list(col = colorRampPalette(region)(100)),
reference.line= list(col = reference),
superpose.line= list(col = symbol),
superpose.symbol = list(col = symbol),
superpose.polygon = list(col = fill, border = fg),
background= list(col = bg),
add.line = list(col = fg),
add.text = list(col = fg),
box.dot = list(col = fg),
axis.line = list(col = fg),
axis.text = list(col = fg),
strip.border = list(col = fg),
box.3d= list(col = fg),
par.xlab.text = list(col = fg),
par.ylab.text = list(col = fg),
par.zlab.text = list(col = fg),
par.main.text = list(col = fg),
par.sub.text = list(col = fg))
modifyList(standard.theme("pdf"), theme)
}

Possibly, but you would have to define what you mean by 'simple' and 'something in between' more precisely. help(trellis.par.set) tells you how to change settings, and you can use it to change all the components you want (and the colors can of course be greyscale). -Deepayan __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Solved using
## Set background color of strips to grayscales:
strip.background <- trellis.par.get("strip.background")
trellis.par.set(strip.background = list(col = grey(7:1/8)))
## Set color of plot symbols to grayscale:
plot.symbol <- trellis.par.get("plot.symbol")
trellis.par.set(plot.symbol = list(col = grey(5/8)))

[R] lattice grayscale "theme"
Hi, is there a grayscale setting for lattice plots? I like the default color settings. I also like the settings that are available for setting black and white with something like this: --8<---cut here---start->8--- ltheme <- canonical.theme(color = FALSE) ## in-built B&W theme ltheme$strip.background$col <- "transparent" ## change strip bg lattice.options(default.theme = ltheme) ## set as default --8<---cut here---end--->8--- Is there a simple way of achieving something in between these settings (using grayscales for the default colors)?
