R help - Jul 2002 - controling graphic window size and asprec ratio in windows

i am using the rarcinfo package
to draw maps.
for maps, th aspect ratio is quite important.
how can i control the aspect ratio and the size of a graphics window
in the mswindows version of R and more generally in R in general.
i would like to e able to both set the size before or while the window 
is corrected,
and also for a window which already exists.

Hope your keyboard is repaired very soon!

See plot.windows ( , asp=).  plotarc, plotpal, and plotpoly in RArcInfo
should probably set up with asp=1.

I just ran into that with my GDAL package. Here's an excerpt:

  par.in <- par(no.readonly = TRUE)

  if (reset.par) on.exit(par(par.in))

  par(pin = max(par.in$pin)
      * par.in$fin / max(par.in$fin)
      * rev(plot.dim) / max(plot.dim))

plot.dim gives the rows and cols of the image data. There are some other
adjustments that one could make, but note that if you manually resize
the plot window, the aspect ratio (from R's perspective) does not
change--you have to start a new plot window with the specified size.
