In ajstamm/gatpkg: Geographic Aggregation Tool (GAT)

Combine GAT Crosswalks

Description

This function provides complete crosswalk and final shapefiles in cases when the user requires GAT to be run twice (for example, a first run that enforces the boundary variable and a second run that does not).

Usage

combineGATcrosswalks(path, file1, file2, idvar)

Arguments

path	The filepath to the files created by GAT. This function assumes the same filepath was used in both runs.
file1	The crosswalk (*in) file created in the first run of GAT. For best results, avoid filenames containing a period. It is not necessary to add the file extension.
file2	The crosswalk (*in) file created in the second run of GAT. For best results, avoid filenames containing a period. It is not necessary to add the file extension.
idvar	The ID variable used when running GAT. This function assumes the same ID variable was used in both runs.

Details

Two shapefiles are created and saved in the path provided:

• a revised original crosswalk

  • name: file1 ending in "_combined"

  • "GATid" renamed to "tempid"

  • new "GATid" created with the IDs from the second run

• a revised final aggregation

  • name: file2 without "in" ending in "_combined"

  • "GATnumIDs" removed

  • new "GATnumIDs" created with the number of areas in the original shapefile included in each final area

In a future iteration, I may also include maps and a log that compare the original and final shapefiles.
