Have you reviewed the Spatial Task View on CRAN, and considered posting on the 
R-sig-geo list? It is quite likely that the easiest way to do this is to 
represent your data as an appropriate object, then to see which dimension(s)
you want to run over (possibly the t, but a spatial filter would run over
others). If you need to do a lot of this, you'll save time by thinking through 
representation carefully, and seeing whether R is the best platform for you
for this task.
