R: Variance of genealogical implex

gen.implexVar {GENLIB} | R Documentation

## Variance of genealogical implex

### Description

Returns the variance of the implex index across probands.

### Usage

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

### 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="F" (default), all ancestors will be considered. If onlyNewAnc="T", 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.

### Value

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