Cyndy--
The R package I am aware of for spatially-balanced sampling is spsurvey,
not gpsurvey.

If that is what you are using, there is a wealth of information on the US
EPA Aquatic Resources Monitoring website of the developers (Tony Olsen, Don
Stevens, Tom Kincaid, et al.), including fully-worked examples for finite
points, linear frames, and spatial/areal frames.  One starting point is:
http://www.epa.gov/nheerl/arm/designpages/design&analysis.htm
or directly to grts at:
http://www.epa.gov/nheerl/arm/designing/design_intro.htm

The cran page includes 9 vignettes:
http://cran.r-project.org/web/packages/spsurvey/index.html

Finally, I support NPS Inventory & Monitoring colleagues, many of whom use
spsurvey (and a few of whom use my help).  While the government is not shut
down, the IT daemons are smiling, and I'm too busy to upload my new set of
R for Natural Resources pages, I have a somewhat outdates page available at:
http://science.nature.nps.gov/im/datamgmt/statistics/r/advanced/GRTS.cfm
At some point in the future they will move to somewhere else starting from
http://science.nature.nps.gov/im/datamgmt<http://science.nature.nps.gov/im/datamgmt/statistics/r/advanced/GRTS.cfm>

If those resources don't help you, or if your problem is specific R coding
for getting your sample frame set up correctly and then the design
specified correctly for spsurvey::grts(), post a specific question to this
list and someone should be able to help you.
