individuals: individuals present in the group In EloRating: Animal Dominance Hierarchies by Elo Rating

Description

returns IDs, number or IDs, or CV of number of present individuals

Usage

 ```1 2``` ```individuals(eloobject, from=eloobject\$misc["maxDate"], to=NULL, outp=c("N", "IDs", "CV")) ```

Arguments

 `eloobject` result from `elo.seq` `from` from which date onwards should the ID statistics be calculated. By default the first date in the sequence is used `to` until which date should the ID statistics be calculated. By default `NULL`, i.e. the returned information refers to only the date specified by `from` `outp` one of three options to determine which kind of information is returned: (1) `"N"`: the (average) number of individuals present, (2) `"IDs"`: the actual IDs, and (3): `"CV"`: coefficient of number of individuals present

Details

if `to=NULL`, either the IDs (`outp="IDs"`) or the number of individuals (`outp="N"`) present on this day is returned. `outp="CV"` is not defined in such a case (returns `NA`).

if a `to` date is set (i.e. different from `NULL`), either the IDs of all individuals that were present on at least one day of the date range (`outp="IDs"`) is returned or the average number of individuals present during this time (`outp="N"`). If `outp="CV"`, the coefficient of variation of the number of individuals present is returned, which might be considererd another measure of stability on the group level.

Value

numeric or character
