I'm trying to use the vcd package to produce mosaic plots for my class notes, written in Sweave and using the LaTeX's beamer document class. For projecting the notes in class, I use a dark background with light foreground colors. It's easy enough to change the defaults for R's standard graphics to match my color scheme (using the fg, col.axis, col.lab, col.main, and col.sub parameter settings), but I can't figure out how to do this with grid/strucplot/vcd.>From my experiments, I think that I might eventually figure out how tochange the colors of all the text in the mosaic plots to what I want using arguments like 'gp_args = list(gp_labels = gpar(col = "yellow")' and 'gp_varnames = gpar(col = "yellow")' (although I still haven't figured out how to changed the color of the text on the legends), but this is obviously not what I need. I have been reading all the documentation I can find, but I still haven't figured this out, so an answer accompanied by a reference to some line or the other in some piece of documentation would be greatly appreciated.
You might want to check out package {tikzDevice} and it's
documentation. In essence you turn your R plots to tikz-pgf so they
can be naturally incorporated into a beamer presentation. Colors, bg,
fonts etc. can now be controlled in your main latex doc. I find it
much more convenient, and nicer when the plot annotations make use of
the same latex font rather than e.g. plotmath. Note, for grid graphics
you'll need to use print(yourplot) to the device.
Cheers

The following example promises at least partial (if ugly) success ... library(vcd) pushViewport(viewport(gp=gpar(col="yellow"))) mosaic(Titanic, newpage=FALSE) You can similarly set up font defaults. See "Non-standard fonts in PostScript and PDF graphics" in http://cran.r-project.org/doc/Rnews/Rnews_2006-2.pdf for an example, plus also possibly http://www.stat.auckland.ac.nz/~paul/R/CM/CMR.html.
