You need print() if you are using grid-based graphics (lattice, 
ggplot2,...) in a script.  You are using classic graphics so it should 
not be necessary.

If you are getting blank plots when you shouldn't, that's a bug.  If you 
can put together a reproducible example that shows its a bug in R, 
rather than a bug in your script, it will likely be fixed fairly quickly.
