alarmdata provides utility functions to download and process data produced by the ALARM Project, including 2020 redistricting files and 50-State Redistricting Simulations.
You can install alarmdata with:
install.packages("alarmdata")
You can also install the development version from GitHub with:
# install.packages("remotes")
::install_github("alarm-redist/alarmdata") remotes
We can easily download simulation data for a state and make some plots.
library(alarmdata)
library(redist)
= alarm_50state_map("WA")
map_wa = alarm_50state_plans("WA")
plans_wa
redist.plot.plans(plans_wa, draws=1:4, shp=map_wa)
hist(plans_wa, e_dem) +
::labs(x=NULL, title="Expected Democratic seats") ggplot2
Downloads will go to options(alarm.cache_dir)
if it is
set. If it is not, and options(alarm.use_cache = TRUE)
,
downloads will be cached between sessions in
rappdirs::user_cache_dir("alarm")
. If If
options(alarm.use_cache = FALSE)
(the default), then the
cache will be in a temporary directory that does not persist between
sessions. You can check the size of the cache and clear it with
alarm_cache_size()
and
alarm_cache_clear()
.
