Dear All,

I wonder if someone can point me in the right direction here.  I'm working
with the rms library, R 2.9.2 under Windows XP.

I'm trying to arrange two plots side by side for a colleague.  mfrow or
mfcol do not seem to work, however, so I am obviously missing something
important.  I know that there have been changes in the graphics from Design
to rms, but am just not sure where to find specific documentation about this
particular issue.

Below is the code I'm using.  If I run the code except for the last plot
call, the first plot is correctly produces in the first column with empty
space for the second plot in col 2.  But when I add the second plot call, it
just overwrites the first plot in col1 on the left.

If I run the code below using something like plot(x~y) and plot(a~b) instead
of the two rms summary objects, it works fine, so I am assuming there is
something about rms I am missing.

I'd be happy to provide some data if that would help.

Any guidance would be greatly appreciated.

Thanks,
