Description Usage Arguments Value Author(s) Examples
This function calculates Beta irreplaceability. Inputs can be either a vector
of Alpha values, or a data.frame
containing all necessary parameters
needed to calculate Alpha values on a row-by-row basis.
Vector Beta measurement: If data
is a vector of Alpha
irreplaceability values, a single Beta value will be calculated and
returned.
Dataframe Beta measurement: If data
is a
data.frame
and local
, global
and target
are
strings representing field names in data
, a vector of Alpha
irreplaceability values will be caluclated using these fields, and a Beta
irreplaceability value will be calculated on these, and returned.

logical - Should features with unachievable targets be ignored? Defaults to FALSE. If FALSE, these species will be always assigned an Alpha irreplaceability of 1 wherever they occur. If TRUE, these species will always be assigned an Alpha irreplaceabiltiy of 0. |
