An R client for the Political Science Replication Index, a searchable, tagged index of replication packages crawled monthly from 34 flagship political science journals' Harvard Dataverse collections.

Installation

# install.packages("pak")
pak::pak("jsakowuah/psreplicate")

Usage

library(psreplicate)
# search by free text, journal, method, data type, and/or year
search_replications(query = "regression discontinuity", journal = "AJPS")
search_replications(method = "Survey Experiment", year = 2020:2024)
# see what's covered
list_journals()
# force a re-download of the index (otherwise it auto-refreshes daily)
refresh_index(force = TRUE)

The index is downloaded once and cached in a per-user cache directory (tools::R_user_dir("psreplicate", "cache")), so repeated calls to search_replications() and list_journals() don't need network access.
