## Expected Genealogical Depth

### Description

Returns the expected genealogical depth.

### Usage

    gen.meangendepth( 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), mean genealogical depth over all specified probands is calculated. If type="IND", mean 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.
