Hello R help list

I have been using the smoothScatter function within the "geneplotter"
package to make some graphs using a Sweave Rnw script called via Rscript
in a DOS/Windows batch file.  The Rscript will ultimately be called by a
web service with time-out constraints, hence things need to run as
swiftly as possible.

The geneplotter package is currently loaded each time R is invoked and
has quite a number of dependencies, of which only one (namely Kernsmooth
package) appears to be necessary for the smoothScatter command to work.

As loading all these superfluous packages (for my purposes at least)
takes a bit of time - is there a way to turn off the loading of
dependent packages so that I can only load the minimum ones I need?  I
understand I'll be carrying the risk of missing dependencies but in this
case it is fairly straight forward as to why I need to do this and what
specific packages are needed.

Any suggestions?
