create_leaderdays: Create leader-days from leader data

Description

create_leaderdays() allows you to generate leader-day data from leader-level data provided in peacesciencer.

Usage

create_leaderdays(system = "archigos", standardize = "none")

Value

create_leaderdays() takes leader-level data available in peacesciencer and returns a leader-day-level data frame.

Arguments

system

a leader system with which to create leader-days. Right now, only "archigos" is supported.

standardize

a character vector of length one: "cow", "gw", or "none". If "cow", the function standardizes the leader-days to just those that overlap with state system membership in the Correlates of War state system (see: cow_states). If "gw", the function standardizes the leader-days to just those that overlap with the state system dates of the Gleditsch-Ward date (see: gw_states). If "none", the function returns all leader-days as presented in Archigos (which is nominally denominated in Gleditsch-Ward state system codes, if not necessarily Gleditsch-Ward state system dates). Default is "none".

Details

create_leaderdays(), as of writing, only supports the Archigos data set of leaders. I envision this function being mostly for internal uses. Basically, create_leaderyears() effectively starts by first running a version of create_leaderdays(). So, why not have this function too?

The Archigos data are anchored in the Gleditsch-Ward system of states, which now includes (in this package by way of isard) the microstates. However, the Archigos data do not include information for the leaders of microstates.
