estPopSize: Estimate population size at the whole area

In Xinhai-Li/abundanceR: Estimate wildlife abundance based on distance sampling and species distribution models

Estimate population size at the whole area

Description

Predict the population size using a species distribution model, and adjust the predicted value based on real observations by distance sampling

Usage

estPopSize(pop.pred, tracks, species, detection)

Arguments

pop.pred	A raster layer with number of individuals at each cell
tracks	A dataframe containing the Lat/Lon of thinned track points.
species	A data.frame of species occurrences with columns "Name_E", "Lon", "Lat", "Date", "Count"
detection	The average detection during distance sampling

Value

A vector including the predicted population size by Random Forest, predicted population on the routes, Observed population on the routes, and final adjusted estimation of population size
