In peacesciencer: Tools and Data for Quantitative Peace Science Research

Add Correlates of War war data to dyad-year or state-year data frame.

Description

add_cow_wars() allows you to Correlates of War data to a dyad-year or state-year data frame

Usage

add_cow_wars(data, type, intratype = "all")

Arguments

data	a data frame with appropriate peacesciencer attributes
type	the type of war you want to add. Options include "inter" or "intra".
intratype	the types of armed conflicts the user wants to consider, specified as a character vector. Options include "local issues" and "central control". Applicable only if type is "intra".

Details

Intra-state war data are coerced into true state-year data by first selecting the duplicate state-years on unique onsets, then whichever war was the deadliest. The inter-state war data work functionally the same way.

On intra-state wars: the primary_state is used to identify the government principally fighting the domestic non-state actor over central control over local issues. Internationalized civil wars are included in the data, but not for outside actors that intervene on behalf of the government or rebel group.

Extra-state war functionality is not available right now as I try to figure out the demand for its use.

Value

add_cow_wars() takes a dyad-year or state-year data frame and returns information about wars from either the inter-state or intra-state war data set from the Correlates of War. The function works for state-year data when the user wants information about extra-state wars or intra-state wars. The function works for dyad-year data when the user wants information about inter-state wars.
