[R] resizing a plot area when using mfrow

[Rajarshi Guha]

Hi,
  I'm trying to plot two graphs next to each other using the plot()
command. I've used 

par(mfrow=c(1,2),pty='s')

to get the plots on 1 row.
However what happens is that I get a large plot area with the 2 plots in
the center of it, so there is a large amount of white space above and
below the plots.

Currently I take the EPS and then cut out the white boundaries in a
image manipulation program. 

Is there someway I can specify in R that the plot area should resize to
just enclose the row of plots without generating large areas of
whitespace?

Thanks,
