Correlates of War Non-Directed Dyad-Year International Governmental Organizations (IGOs) Data

Description

This is a non-directed dyad-year version of the Correlates of War IGOs data. I use it internally for merging IGOs data into dyad-year data.

Usage

cow_igo_ndy

Format

A data frame with 917695 observations on the following 4 variables.

ccode1

the Correlates of War state system code for the first state

ccode2

the Correlates of War state system code for the second state

year

the year

dyadigos

the sum of mutual IGOs for which each state appears as a full member in a given year

Details

The data-raw directory on the project's Github contains additional information about how these data were generated from the otherwise enormous dyad-year IGOs data provided by the Correlates of War project. Given the size of that data, and the size limitations of R packages for CRAN, the data I provide here can only be simpler summaries. If you want specifics, you'll need to consult the underlying raw data provided on the Correlates of War project.
