cow_gw_years {peacesciencer}

Correlates of War and Gleditsch-Ward states, by year

Description

This is a complete (I believe) data set on Correlates of War states and Gleditsch-Ward states, a byproduct of a full_join() between gw_states and cow_states that leans largely on the state abbreviation variable.

Usage

cow_gw_years

Format

A data frame with 16936 observations on the following 6 variables.

gwcode

a Gleditsch-Ward state code

stateabb

the state abbreviation, which was the greatest source of agreement between both data sets

gw_statename

the state name as it appears in the Gleditsch-Ward data

ccode

a Correlates of War state code

cow_statename

the state name as it appears in the Correlates of War data

year

a numeric vector for the year

Details

The data-raw directory on the project's Github contains more information about how these data were created. I'm going to use it for internal stuff. The workflow is going to treat the Correlates of War state system membership codes as more of the "master" codes, for which the user can add Gleditsch-Ward identifiers as they see fit. Data are extended to 2020, assuming no changes to state system membership for either data set.
