gen.meangendepthVar: Variance of genealogical depth

In GENLIB: Genealogical Data Analysis

Variance of genealogical depth

Description

Returns the variance of the genealogical depth

Usage

gen.meangendepthVar( gen, pro = "0", type = "MEAN", ...)

Arguments

gen	An object of class GLgen obtained with gen.genealogy, gen.lineages or gen.branching. Required.
pro	Vector of proband id numbers to be included. Default is 0, which will select all individuals without children.
type	If type="MEAN" (default), the average of genealogical depth variances (over all probands) is returned. If type="IND", the variance of the genealogical depth is calculated for each specified proband.
...	Option to pass additionnal arguments automaticaly between methods. Internal use only.

Value

A data frame with only one numeric value when type is "MEAN". When type is "IND", the number of rows equals the number of probands specified.
