Load leader data

Source: R/leader_data.R
load_leader_data.Rd

Loads country-year leader data from one of two datasets included with the package. Each row in the output represents one country-year, with the leader who held power at the end of the year. When multiple leaders served in the same year (i.e., a leadership transition occurred), the leader with the latest start date is retained.

Usage

load_leader_data(
  start_year = 1945,
  end_year = 2015,
  dataset = c("archigos", "reign"),
  coding_system = c("cow", "gw")
)
