Add Archigos political leader information to dyad-year and state-year data

Description

add_archigos() allows you to add some information about leaders to dyad-year or state-year data. The function leans on an abbreviated version of the data, which also comes in this package.

Usage

add_archigos(data)

Arguments

data

a dyad-year data frame (either "directed" or "non-directed") or state-year data frame

Details

The function leans on attributes of the data that are provided by the create_dyadyear() or create_stateyear() function. Make sure that function (or data created by that function) appear at the top of the proverbial pipe.

Value

add_archigos() takes a dyad-year or state-year data frame and adds a few summary variables based off the leader-level data. These include whether there was a leader transition in the state-year (or first/second state in the dyad-year), whether there was an "irregular" leader transition, the number of leaders in the state-year, the unique leader ID for Jan. 1 of the year, and the unique leader ID for Dec. 31 of the year.
