mxcp_df: Max-method and relaxed max-method county assignments.
In davidsovich/usgeogr: An R package for U.S. geographic data.

Description Usage Format Source

A dataset that assigns each border county to a unique cluster using the "max-method" algorithm and the "relaxed max-method" algorithm. See vignette for description of the algorithm. Max-method clusters are identified by mxcp_id; relaxed max-method clusters are identified by relaxed_mxcp_id. If there is only one county in a cluster, then the algorithm assigns the identifier to be NA. Metadata: (1) 256 unique non-null max-method and relaxed max-method clusters, (2) 296 counties without an assigned max-method cluster, (3) 120 counties without an assigned relaxed max-method cluster, (4) 85 (80) max-method (relaxed max-method) clusters with 2 constituent counties, 62 (58) with 3 counties, 53 (52) with 4 counties, 32 (32) with 5 counties, 14 (30) with 6 counties, 7 (22) with 7 counties, 1 (8) with 8 counties, 1 (2) with 9 counties, and 1 (1) with 10 counties.

mxcp_df

A data frame with 1,184 rows and 6 variables:

fips_code: County FIPS code, in original string format. Unique identifier.
county_state: State postal code corresponding to FIPS code.
mxcp_id: Max-method cluster identifier.
relaxed_mxcp_id: Relaxed max-method cluster identifier.
mxcp_remove_flag: Binary flag equal to one if a county is unmatched to a max-method cluster with at least two constituent counties.
relaxed_mxcp_remove_flag: Binary flag equal to one if a county is unmatched to a relaxed max-method cluster with at least two constiuent counties.
