           Summary: Eval: subplots from RExpression overly condensed

Using nightly build 14 Apr 08 under WinXP.  The code below generates a
publication-quality graphic when run from the R command line.  When run in an
RExpression actor, however the results are pretty unattractive.  

Case 1: With an imageJ actor connected, the resulting RExpressionNUM.png is
extremely compressed.  i.e., there is lots of white space and the subplots are

Case 2: With no imageJ actor, and the "Automatically display graphics" button
checked, the resulting pdf is less cramped than the png, but still not as
well-proportioned as that coming directly from R.

Note:  resizing the graphic does not help - proportions remain the same

# test code for RExpression actor subplot generation
# get data and variables in order...
library(MASS) ;
names(wtloss) ;         attach(wtloss) ;
w<-Weight ;             d<-Days ;
# set up stacked subplotting environment, plot top fig
par(mfrow=c(2,1)) ;     plot(w~d) ; 
res<-lm(w~d) ;          abline(res) ;
# plot bottom fig
r<-residuals(res) ;     plot(d,r) ;
# return to default graphics, clean up
par(mfrow=c(1,1)) ;
detach(wtloss) ;
