In thomasdenis973/FormatDataToGDS: Format Data To gdistsamp function

Description

Estimate species density using gdistsamp function (package unmarked).

Usage

SpeciesDensityEstimation(data, modelGDS = "NB", methodGDS = "BFGS",
  keyfunGDS = "halfnorm", ...)

Arguments

data	A FDataYGDS object.
modelGDS	Either "P" or "NB" for the Poisson and negative binomial models of abundance. "NB" by default. See ? gdistsamp.
methodGDS	Optimization method used by optim. "BFGS" by default.
keyfunGDS	One of the following detection functions: "halfnorm", "hazard", "exp", or "uniform". "halfnorm" by default. See ? gdistsamp.
...	This function used CreateDataYGDS function with default arguments. See ? CreateDataYGDS.

Value

Return a list with an object of class unmarkedFitGD, a vector with IKA (Encounter rate for 10 km), a vector with abundance in km^2 estimated by ranef function (package unmarked).
