This vignette is meant to provide useRs with an visual, explorable introduction to the capabilities of the igoR package.

The analysis would be based on those provided on [@pevehouse2020]. For more information on the IGO data sets and additional downloads, see Intergovernmental Organizations (v3).

Note that the dyadic dataset is not provided in the package, due its size (\~500 MB on Stata .dta format). However, igo_dyadic() function provides similar results.

Definitions

From @pevehouse2019:

What is an IGO?

The definition of an Intergovernmental Organization (IGO) on the original dataset is based on the following criteria:

1. An IGO must consist of at least three members of the COW-defined state system.

2. An IGO must hold regular plenary sessions at least once every ten years

3. An IGO must possess a permanent secretariat and corresponding headquarters.

When does an IGO actually begin?

The data sets begins to code an IGO by identifying the first year in which the organization functions. In some cases, individual members are listed by year of accession or signature.

When does an IGO die?

Version 3.0 of the IGO data set uses the following criteria:

• An organization is considered terminated when the following words were used to describe the context of the organization:

  • Replaced;
  • Succeeded;
  • Superseded;
  • Integrated;
  • Merged;
  • Dies.

Analysis

This section provides some quick analysis based on the figures of @pevehouse2020.

IGOs overview

The following code extracts the number of IGOs and states included on this package. The years available are 1816 to 2014.

# Summarize
igos_by_year <- igo_year_format3 %>%
  group_by(year) %>%
  summarise(value = n(), .groups = "keep") %>%
  mutate(variable = "Total IGOs")

countries_by_year <- state_year_format3 %>%
  group_by(year) %>%
  summarise(value = n(), .groups = "keep") %>%
  mutate(variable = "Number of COW states")

all_by_year <- rbind(igos_by_year, countries_by_year) %>%
  mutate(variable = factor(variable))

# Reverse values
all_by_year$variable <- factor(all_by_year$variable,
  levels = rev(levels(all_by_year$variable))
)

# Plot

IGO Births and deaths

This plot shows how many IGOs were "born" and "died" on each year

# Births and deads by year

df <- igo_search()

births <- df %>%
  mutate(year = sdate) %>%
  group_by(year) %>%
  summarise(value = n(), .groups = "keep") %>%
  mutate(variable = "IGO Births")

deads <- df %>%
  mutate(year = deaddate) %>%
  group_by(year) %>%
  summarise(value = n(), .groups = "keep") %>%
  mutate(variable = "IGO Deaths")


births_and_deads <- rbind(births, deads) %>% filter(!is.na(year))


# Plot
ggplot(births_and_deads, aes(x = year, y = value)) +
  geom_line(color = "black", aes(linetype = variable)) +

IGOs across regions

A plot with the number of IGOs by region. The definition of region is based on the original definition by @pevehouse2020.
