marxan_alphas: Marxan: Alpha irreplaceabilities

In proxirr: Alpha and Beta Proximity to Irreplaceability

Description

Given a valid Marxan input.dat file, it returns a copy of the PUVSPRNAME file (puvspr.dat), with additional columns containing the feature's global value, target value, and alpha irreplaceability.

Usage

marxan_alphas(input, triage = FALSE)

Arguments

input	string - The address of the input.dat file.
triage	logical - Should features with unachievable targets be given an irreplaceability of 0? See alpha.

Details

The global value is obtained as the sum of the feature's "amount" column in PUVSPRNAME.

The target value is obtained from the SPECNAME file (spec.dat), either as the proportion of the global value (if the "prop" column is present in SPECNAME), or as the "target" value in SPECNAME (otherwise). This behaviour mirrors Marxan's default behaviour.

Value

A data.frame
