For more than one on a page, see ?par, in particular its argument "mfrow".

Starting the device with postscript(),  plotting with hist() and closing 
with dev.off() should produce something, if you haven't done very 
strange things.

Try:
  postscript("ex.eps")
  hist(1:10)
  dev.off()

Now look into the eps file. Is it still empty? Then something is wrong 
with either your postscript interpreter or your setup of R.
