• Fixes an NA matching error within get_lewis() that would break downloads for certain congress-state pairs (#17).
• Expands inline documentation to provide better descriptions of arguments and goals of functions.

geomander 2.5.2

CRAN release: 2025-12-11

• Fixes a CRAN download issue for invalid links for Lewis, DeVine, Pitcher, and Martis shapefiles.

geomander 2.5.1

• Fixes an issue where block2prec() would fail if there were units in to that had no matches in from.

geomander 2.5.0

CRAN release: 2025-09-01

• Adds large speed improvements to geo_match().

geomander 2.4.0

• Replaces magrittr pipe with the base R pipe internally and in examples.
• Improves handling of columns within block2prec().

• 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

CRAN release: 2022-06-23

• 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

CRAN release: 2021-12-08

• 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().
