This is a simple data set that communicates directed dyads in the Gleditsch-Ward system that appear in the same year, but not in any particular day in the year. They are used in an anti-join in the create_dyadyears() function in this package.

Usage

false_gw_dyads

Format

A data frame with the following six variables.

gwcode1

a numeric vector for the Gleditsch-Ward state code for the first state

gwcode2

a numeric vector for the Gleditsch-Ward state code for the second state

year

a numeric vector for the year

microstate1

a numeric vector that equals 1 if the first state in the dyad is a micro-state. 0 if otherwise.

microstate2

a numeric vector that equals 1 if the second state in the dyad is a micro-state. 0 if otherwise.

in_ps

a constant that equals 1 if these data would appear in create_dyadyears() if you were not careful to remove them.

Details

Think of the directed Serbia and Yugoslavia dyad from 2006 as illustrative here. The Gleditsch-Ward system ends Yugoslavia June 4, 2006 and re-enters Serbia (its rump state) on June 5, 2006. How to treat Serbia/Yugoslavia is one of the clearest differences between the Correlates of War system and the Gleditsch-Ward system, and understanding how the Gleditsch-Ward system treats this case matters a great deal in creating dyad-year data. There should obviously be no Serbia-Yugoslavia dyad when Serbia is the rump state of Yugoslavia that Gleditsch-Ward re-enter into their system when Montenegro split from it and enters the state system on June 3, 2006. Both Serbia and Yugoslavia existed in 2006, but not on the same day in the same year.
