`candidates`	character vector of IDs of the animals available for use in the group.
`currentGroups`	list of character vectors of IDs of animals currently assigned to the group. Defaults to character(0) assuming no groups are existent.
`kin`	list of animals and those animals who are related above a threshold value.
`ped`	dataframe that is the 'Pedigree'. It contains pedigree information including the IDs listed in `candidates`.
`harem`	logical variable when set to `TRUE`, the formed groups have a single male at least `minAge` old.
`minAge`	integer value indicating the minimum age to consider in group formation. Pairwise kinships involving an animal of this age or younger will be ignored. Default is 1 year.
`numGp`	integer value indicating the number of groups that should be formed from the list of IDs. Default is 1.
`sexRatio`	numeric value indicating the ratio of females to males x (from 0.5 to 20 by increments of 0.5 within the accompanying Shiny application. A sex ratio of 0 ignores sex in making up groups.
