Thanks, this comment clarifies things somewhat. 
Though I find it
an odd design choice for R, since it seems to entail
then that
the user has figure out the aspect ratio of the
resulting plot,
something that R could easily keep track of as it is

Here's example code, producing 3 scatterplots
(here reusing the same plot for simplicity).   

What's desired is that the individual scatterplots
have the
natural aspect, e.g. square, with the axis units being
same for X, Y.   And to do this while producing a
bounding box in the .eps file.   

As it stands the example code produces a correct
bounding box,
but the scatterplots are too stretched to be usable.  
aspect=1/1 in the xyplot() seems to cause the bounding
to be  incorrect.



rand1 <- rnorm(50)
rand2 <- rnorm(50)
theplot <- xyplot(rand1 ~ rand2, xlab="x axis",
ylab="y axis")

thefile <- "plotproblem.eps"
trellis.device(postscript, file=thefile, color=F,
print(theplot, split=c(1,1,3,1), more=T)
print(theplot, split=c(2,1,3,1), more=T)
print(theplot, split=c(3,1,3,1), more=F)
