I used the rgdal package to open a geoTiff and then manipulate the
data. The result is a 3-dimensional array that I want to convert back
to a SpatialGridDataFrame in order to save it as a geoTiff. I used
the following code:
grd <- GridTopology(gt[,1],gt[,2],gt[,3])
SGDF <-

I think creative use of the overlay() function would accomplish what you want.
Some example code that is a bit like what you propose (uses the sp library):
# I have a polydataframe object:
my.poly.data <- SpatialPolygonsDataFrame(my.poly, area.lu.table)
# I have a set of point objects (derived, i
