stratum	The name of the stratum to partition on (default="Population").
longitude	The column name of the longitude
latitude	The column name of the latitude
as.SpatialPoints	A flag indicating what kind of coordinates to return should be turned into a SpatialPoints object (TRUE) or as a data.frame (FALSE, the default)
sort.output	A flag indicating if the results should be sorted alphabetically (default=FALSE)
