presence_absence: This function estimates presence or absence at each transect

In rooperc4/MEHRSI: Habitat Model Estimates of Survey Abundances

Description

This function uses the cdf_limits function to calculate the limits of presence or absence for a species based on a variable of interest. For example, if the cdf_limits found that a species was only present at depths between 100 m and 200 m, this function would input the depths from a trawl survey haul and determine presence or absence or absence of the species at that site.

Usage

presence_absence(variables, limits)

Arguments

variables	Variables used for determining presence or absence
limits	Limits on the distribution of a species from cdf_limits function

Examples
