[Tikzdevice-bugs] tikz and grid/lines/axis?

[Charlie Sharpsteen]

Hi Matthieu,

It appears you have found a bug.  What happens is that the call to
tikz() opens a new .tex file and draws an invisible rectangle that is
the size of the plotting canvas.  As Cameron mentioned, it looks like
we figured R graphics functions would come along and fill in a
background if they wanted some color.  We never noticed this wasn't
happening because we mostly use our plots in reports that are printed
out on white paper.

I tried to find a workaround at the R level---but no luck so far as
this stuff all happens at the C level.  For right now Cameron's
suggestion is the only way I can think of to change the background
color.  I will work on a fix for this issue and we will release a
0.6.1 to CRAN as soon as it is done as this is pretty major.

Thanks for taking the time to try our package and the extra time to
report this bug!
