geomander 2.4.0

  • Replaces magrittr pipe with the base R pipe internally and in examples.
  • Improves handling of columns within block2prec().
  • Adds an attribute to geo_match() when the last precinct in to is not matched. This can later be used when filling missing precincts (the implicit 0s).

geomander 2.3.0

  • Adds support for downloading Jeffrey B. Lewis's historical congressional districts with `get_lewis()
  • Adds support for downloading RPV Near Me datasets with get_rpvnearme()
  • Corrects normalized global Moran's I calculation (#12), thanks @CoryMcCartan.
  • Fixes a download issue for get_dra()

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

geomander 1.0.5

  • adds orange dataset to bring back a vignette
  • 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.
