In ajstamm/gatpkg: Geographic Aggregation Tool (GAT)

Find the Weighted Centriod for a GAT Region

Description

This function identifies the population weighted centroid of a new area based on the GAT ID assigned to the old areas and the population shapefile.

Usage

weightGATregion(area, pop, IDlist, idvar, nrid)

Arguments

area	The original shapefile.
pop	The base population shapefile.
IDlist	The list of all GAT IDs and their corresponding area IDs.
idvar	A variable of unique string values to identify the observations.
nrid	A string that will be the ID for the merged observation (polygon).

Examples

ids <- c("e", "e", "d", "d", "f", "f", "f", "e", "e", "d", "e",
         "d", "b", "c", "c", "a", "b", "c", "a", "b", "c")
mycentroid <-
  weightGATregion(
    area = hftown,
    pop = hfpop,
    IDlist = ids,
    idvar = "ID",
    nrid = "c"
  )
