organizePolygons

Object of class SpatialPolygonsDataFrame.

SPDF

Unique identifier to determine which values are duplicated.

uniqueID

Vector of column names to be summed.

sumColumns

Determines if the SpatialPolygonsDataFrame is grouped. If ungrouped,
function will group duplicated values based on the provided unique identifier.
If <code>sumColumns</code> is NULL and there are multiple rows that aren't
duplicated but have the same <code>uniqueID</code>, the original
SpatialPolygonsDataFrame will be returned.

internal

A suite of conversion functions to create internally standardized
spatial polygons data frames. Utility functions use these data sets to
return values such as country, state, time zone, watershed, etc. associated
with a set of longitude/latitude pairs. (They also make cool maps.)
