In LimaRAF/plantR: Managing Species Records from Biological Collections

Automatic Detection of Spatial Outliers

Description

This is a local copy of the function mvoutlier::arw(), that implement adaptive reweighted estimator for location and scatter with hard-rejection weights. It is only used in one specific function of plantR: distOutlier().

Usage

arw1(x, m0, c0, alpha = 0.025, pcrit)

Arguments

x	a data frame with longitude and latitude in decimal degrees
m0	center of the distribution
c0	covariance matrix (p x p) of the distribution
alpha	Maximum thresholding proportion. Default to 0.025.
pcrit	Critical value obtained by simulations
