R/add_archigos.R
add_archigos.Rdadd_archigos() allows you to add some information about leaders to dyad-year
or state-year data. The function leans on an abbreviated version of the data, which also comes in this package.
add_archigos(data)
| data | a dyad-year data frame (either "directed" or "non-directed") or state-year data frame |
|---|
add_archigos() takes a dyad-year or state-year data frame and adds a few summary
variables based off the leader-level data. These include whether there was a leader transition in the
state-year (or first/second state in the dyad-year), whether there was an "irregular" leader transition,
the number of leaders in the state-year, the unique leader ID for Jan. 1 of the year, and the unique leader
ID for Dec. 31 of the year.
The function leans on attributes of the data that are provided by the create_dyadyear() or
create_stateyear() function. Make sure that function (or data created by that function) appear at the top
of the proverbial pipe.
