Designed for easy\npreparation to run simulation analysis with the R package redist, but is\naimed at the geographic aspects of redistricting, not partitioning\nmethods. Most of these tools are gathered from seminar papers and do not\ncorrespond to a single publication.\n\n## Installation\n\nYou can install the released version of geomander from\n[CRAN](https://CRAN.R-project.org) with:\n\n``` r\ninstall.packages(\"geomander\")\n```\n\nAnd the development version from [GitHub](https://github.com/) with:\n\n``` r\n# install.packages(\"devtools\")\ndevtools::install_github(\"christopherkenny/geomander\")\n```\n\n## Examples\n\nA very common task is aggregating block data to precincts.\n\n``` r\nlibrary(geomander)\nlibrary(tidyverse)\n#> ── Attaching core tidyverse packages ──────────────────────── tidyverse 2.0.0 ──\n#> ✔ dplyr 1.1.4 ✔ readr 2.1.4\n#> ✔ forcats 1.0.0 ✔ stringr 1.5.1\n#> ✔ ggplot2 3.4.4 ✔ tibble 3.2.1\n#> ✔ lubridate 1.9.3 ✔ tidyr 1.3.0\n#> ✔ purrr 1.0.2 \n#> ── Conflicts ────────────────────────────────────────── tidyverse_conflicts() ──\n#> ✖ dplyr::filter() masks stats::filter()\n#> ✖ dplyr::lag() masks stats::lag()\n#> ℹ Use the conflicted package () to force all conflicts to become errors\n \n# load precincts\ndata('va18sub')\n\n# create block data\nblock <- create_block_table(state = 'VA', county = '087') \n\n# match the geographies\nmatches <- geo_match(from = block, to = va18sub)\n\n# Aggregate\nprec <- block2prec(block_table = block, matches = matches)\n```\n\nOther important tasks include breaking data into pieces by blocks\nunderlying them.\n\n``` r\nlibrary(geomander)\nlibrary(tidyverse)\n \n# load precincts\ndata(\"va18sub\")\n\n# subset to target area\nva18sub <- va18sub %>% filter(COUNTYFP == '087')\n```\n\nThen we can get common block data:\n\n``` r\nblock <- create_block_table(state = 'VA', county = '087') \n```\n\nAnd estimate down to blocks\n\n``` r\ndisagg <- geo_estimate_down(from = va18sub, to = block, wts = block$vap, value = va18sub$G18USSRSTE)\n```\n\nFor more information, see the documentation and vignettes, available at\n","jobInfo":{"package":"geomander","version":"2.3.0","parsingStatus":"success","parserVersion":2,"parsedAt":"2025-09-01T17:31:06+0000"}}
