gw_ddy {peacesciencer}

A directed dyad-year data frame of Gleditsch-Ward state system members

Description

This is a complete directed dyad-year data frame of Gleditsch-Ward state system members. I offer it here as a shortcut for various other functions. As a general rule, this data frame is updated after every calendar year to include the most recently concluded calendar year.

Usage

gw_ddy

Format

A data frame with the following 3 variables.

gwcode1

a numeric vector for the Correlates of War state code for the first state

gwcode2

a numeric vector for the Correlates of War state code for the second state

year

a numeric vector for the year

Details

Data are a quick generation from the create_dyadyears(system="gw") function in this package.
