transition_paths {ConvergenceClubs}

Extract transition paths from a convergence.clubs object

Description

Given a convergence.clubs object (created by either findClubs or mergeClubs function), returns a list with transition paths for each club.

Usage

transition_paths(
  clubs,
  include_unit_names = TRUE,
  output_type = c("list", "data.frame")
)

Arguments

clubs

an object of class convergence.clubs (created by either function findClubs or mergeClubs).

include_unit_names

logical, if TRUE (the default) adds a column with unit names (only if present in the convergence.clubs object passed to clubs).

output_type

string indicating if the function should output a list or a data frame. Possible options are "list" and "data.frame", default is "list".

Value

If output_type=="list", a list of data frames, one for each club; each data frame will contain transition paths for the units in the correspondent club. If output_type=="data.frame", a data.frame.
