extended_gower: Extended Gower with exceptions

In Andros-Spica/cerUB: Protocols for exploring archaeometric data

Description

Calculate the extended Gower coefficient for archaeometric data sets, considering exceptional values in ordinal variables, using a modified version of dist.ktab.

Usage

extended_gower(data, variable_sets, method = "RRD",
  exception_columns = NULL, exception_values = NULL,
  exception_distance = 0)

Arguments

data	Data frame containing ordinal variables and optionally compositional data (log-ratios).
variable_sets	List containing vectors with the numeric index of variables of different kind.
method	Character, "NI" for neighbour interexchange, "RRD" for relative ranking difference, "MM" for mixed mode.
exception_columns	Numeric, the vector of variables names to be searched for exceptions.
exception_values	Numeric, the value to be set with distance.
exception_distance	Numeric, the index of the variable to be used as divisor in additive log-ratio transformation.
