modSel: Wrapper for function spatSim() which allows use on multiple...

In Biolinv: Modelling and Forecasting Biological Invasions

Description

This function uses spatSim() function to compare many simulated datasets with one, typically observed, data set.

Usage

modSel(WIN, M0, M2, AV, RAD)

Arguments

WIN	window of observation for the point patterns (MOD0 and MOD2)(see ?spatstat.geom::owin). Object of class 'sp::owin'.
M0	data frame containing 'y' and 'x' coordinates (projected coordinate system) to compare with M2.
M2	list of dataframes with same structure of M0, typically generated with simulacro() function.
AV	numeric vector of the Alpha values of the simulated datasets in the same order as in the list of argument M2. Used to save the output data frame.
RAD	numeric vector of search distances for the K-function.

Value

data frame with two columns. 'dissimilarity': dissimilarity values as computed by spatSim() function. 'compAlpha': same as AV.
