Extract the joint membership of a pair of countries across IGOs

Description

Dyadic version of the data. The unit of observation is a dyad of countries. It provides a summary of the joint memberships of two countries across IGOs over time.

Usage

igo_dyadic(country1, country2, year = 1816:2014, ioname = NULL)
igo_dyadic(country1, country2, year = 1816:2014, ioname = NULL)

Arguments

`country1`, `country2`	A state of vector of states to be compared. It could be any valid name or code of a state as specified on states2016.
`year`	Year to be assessed, an integer or an array of year.
`ioname`	Optional. `ioname` or vector of `ioname` corresponding to the IGOs to be assessed. If `NULL` (the default), all IGOs would be extracted. See codes on `igo_search()`.

Details

This function tries to replicate the information contained in the original file distributed by The Correlates of War Project (dyadic_format3.dta). That file is not included in this package due to its size.

The result is a data.frame containing the common years of the states selected via ⁠country1, country2, year⁠ by rows.

An additional column dyadid, computed as (1000*ccode1)+ccode2 is provided in order to identify relationships.

For each IGO selected via ioname (or all if the default option has been used) a column (using lowercase ioname as identifier) is provided with the following code system:

Category	Numerical Value
No Joint Membership	0
Joint Full Membership	1
Missing data	-9
State Not System Member	-1

See igo_recode_dyadic() section for an easy way to recode the numerical values into factors.

If one state in an IGO is a full member but the other is an associate member or observer, that IGO is not coded as a joint membership.

Value

A coded data.frame representing the years and country dyad (rows) and the IGOs selected (columns). See Details.

Differences with the original dataset

There are some differences on the results provided by this function and the original dataset on some IGOs regarding the "Missing Data" (-9) and "State Not System Member" (-1). However it is not clear how to fully replicate those values.

Helper functions to recode categories

Description

These functions convert the numerical code of igo_year_format3 and state_year_format3 into factors.

igo_recode_igoyear() is intended to work with values on igo_year_format3.
igo_recode_stateyear() is intended to work with values on state_year_format3.
igo_recode_dyadic() is intended to work with values on igo_dyadic().

Usage

igo_recode_igoyear(x)

igo_recode_stateyear(x)

igo_recode_dyadic(x)
igo_recode_igoyear(x)

igo_recode_stateyear(x)

igo_recode_dyadic(x)

Arguments

`x`	Numerical value (or vector of values) to recode.

Value

The recoded values as factors.

Examples

Details

This data set contains the list of states in the international system as updated and distributed by the Correlates of War Project.

These data sets identify states, their standard Correlates of War "country code" or state number (used throughout the Correlates of War project data sets), state abbreviations, and dates of membership as states and major powers in the international system.

The Correlates of War project includes a state in the international system from 1816-2016 for the following criteria:

Prior to 1920 the entity must have had a population greater than 500,000 and have had diplomatic missions at or above the rank of charge d'affaires with Britain and France.
After 1920 the entity must be a member of the League of Nations or the United Nations, or have a population greater than 500,000 and receive diplomatic missions from two major powers.

Note

state variable added to original data to help comparison across datasets on this package.
