eiCompare
is an R package built to help practitioners and academics quantify racially polarized voting (RPV) with ease and confidence. It builds on top of several existing packages, augmenting their utility for measuring racially polarized voting in elections. Underlying packages include ei
, eiPack
, and wru
.
eiCompare
was built with several types of users in mind:
*Fixed a bug in tests/testthat/test_wru_predict_race_wrapper.R that fails if there isnt internet to access wru repo data
censusxy
.wru
to ensure compatibility with new versionThe Voting Rights Team of the 2020 University of Washington Data Science for Social Good Fellowship program worked throughout the summer to develop the latest iteration of the package. Highlights from the update include:
See here for a full list of new features.
CRAN submission is currently underway. Check back soon for instructions on installation from CRAN.
Install latest development version with:
remotes::install_github('RPVote/eiCompare')
The name eiCompare
highlights the utility of this package for comparing different ecological inference estimates. For instance, the following code compares iterative and RxC estimates of racial voting preferences in a stylized version of the 2018 Georgia gubernatorial election:
library(eiCompare)
data("gwinnett_ei")
iter <- ei_iter(
data = gwinnett_ei,
cand_cols = c("kemp", "abrams", "metz"),
race_cols = c("white", "black", "other"),
totals_col = "turnout",
name = "Iterative EI",
)
rxc <- ei_rxc(
data = gwinnett_ei,
cand_cols = c("kemp", "abrams", "metz"),
race_cols = c("white", "black", "other"),
totals_col = "turnout",
name = "RxC EI",
)
plot(iter, rxc)
The top panel shows that the majority of white voters voted for Brian Kemp, who won this election. The middle panel shows the estiamted preferences of black voters. The estimates indicate that black voters strongly preferred Stacey Abrams over Brian Kemp.
