In geomander: Geographic Tools for Studying Gerrymandering

geomander 2.2.0

• Updates dependencies for easier installation.
• Allows for use of circle as a method in geo_match().
• Adds a by argument to geo_match() for subsetting to known matching regions.
• Uses redist in vignettes only conditionally.
• Massive improvements in performance for check_contiguity().

geomander 2.1.1

• Fixes missing tolerance bug in geos_circle_center().
• Adds experimental regionalizion approach, regionalize().

geomander 2.1.0

• Avoid indirect download for get_alarm(). Fixes bug where block level data resulted in mismatched geometry.
• Add st_circle_center() and geos_circle_center() for centroid of the maximum inscribed circle.
• Add baf_to_vtd() function to approximate BAFs at the VTD level.

geomander 2.0.2

• Drop spdep dependency to avoid timeouts on checking examples.

geomander 2.0.0

• check_contiguity() orders by most frequent component, so less common components have higher numbers.
• Uses geos for geographic computations over sf to avoid s2 where possible and introduce speed improvements.
• Uses cli package for progress reporting.
• adjacency renamed to adj to match redist naming.
• Updates r2dra and dra2r to work off of 2020 geometries.
• Majority of functions gain epsg argument to project for accuracy relative to projection.

geomander 1.1.2

• Fixes website redirects for CRAN.
• Improves flexibility in block2prec.
• Updates default year to 2020 for create_block_table().
• Adds a polygon contiguity check. Slower than the standard contiguity check, but covers more edge cases.

geomander 1.1.1

• Replace PL94171 import with tigris.

geomander 1.1.0

• Collapse county calls into one for create_block_table()
• Update variables to allow 2000 support in create_block_table()
• Add VEST import tools
• Fix edge case where no geo_match for final entries in estimate_down()
• Add ALARM import tools

geomander 1.0.9

• Address SD and AK create_block_table assumptions

geomander 1.0.8

• downgrade CRS for solaris 2005 build

geomander 1.0.7

• Shortens vignettes for CRAN build speed

geomander 1.0.6

• updates for sf 1.0-0 compatibility
• makes sure all examples run

• brings back 1/2 vignettes
• updates create_tract_table with better names
• begins use of testthat

geomander 1.0.4

• adds rockland dataset containing simplified geometry blocks and precincts
• adds draft split_precinct function (functional but not 100% stable)
• introduces better race column names for create_block_table (tract update planned for 1.0.5)

geomander 1.0.3

• makes vignettes GitHub only to allow for CRAN submission

geomander 1.0.2

• makes geo_filter and geo_trim more stable and consistent
• spell checks

geomander 1.0.1

• speed up suggest_component_connection
• adds functions for using plans with Dave's Redistricting

geomander 1.0.0

• First release of geomander.
