gen.implexVar: Variance of genealogical implex

Description

Returns the variance of the implex index across probands.

Usage

gen.implexVar( gen, pro = "0", onlyNewAnc = FALSE, genNo = -1, ...)

Value

A data frame with one column and each generation at which the variance is calculated as rows

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.
onlyNewAnc: If onlyNewAnc=FALSE (default), all ancestors will be considered. If onlyNewAnc=TRUE, only new ancestors will be counted (i.e., an ancestor is not counted again if it has already been counted in another generation).
genNo: Vector of generation numbers at which the implex should be calculated. Default is -1, which calculates the implex at each generation.
...: Additionnal arguments to be passed to methods.
