Variance of genealogical implex
Description
Returns the variance of the implex index across probands.
Usage
gen.implexVar( gen, pro = "0", onlyNewAnc = FALSE, 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=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. |
Value
A data frame with one column and each generation at which the variance is calculated as rows
