xyplot/levelplot: thickness of tickmarks

if I use the xyplot (or levelplot) function (lattice library) with
the option axs="i", I have the problem that the tickmarks lie a bit
outside the "plot-box". Consider for example:
As you can see at x=1, half of the tickmark is actually to the right
of the "plot-box" (just zoom in to see that...). Sure you can solve
this by using a bigger smaller/bigger value for the ranges of xlim
and ylim, but is there any option/way to fix that? I do not like to
set xlim=c(-0.001,1.001) and ylim=c(-0.001,1.001) which would solve
the problem but this is somehow "dirty". I couldn't find an option
for the thickness of the tickmarks (that would solve the problem as I
think the tickmarks-thickness is just bigger than the thickness of
Any help appreciated
I can't find a simple command to switch the plot colors from paper to
presentation formats. Has anyone defined styles that can be easily applied
in one command?
It would be nice to have a command for papers, using ps or eps outputs, that
has a white background and colors that will print nicely on that. On the
other hand, it would be nice to have exactly the same plot for a
presentation on a black background. A function to flip all the colors to
suit the presentation format would be ideal.
What is the best way to go about this using R?
