Danz2012JVegSci_2D: Estimation of abruptness of the vegetation-transition along...

In dschlaep/ecotoner: ecotoner - ecotones / ecological boundaries across environmental gradients

Description

Implementation of the methods by Danz et al. (2012).

Usage

Danz2012JVegSci_2D(i, b, migtype, ecotoner_settings, etband, etmeasure,
  copy_FromMig1_TF, do_figures, ...)

Arguments

i	An integer value. The number of the ecotone transect; a value smaller than or equal to transect_N(ecotoner_settings).
b	An integer value. The index of the neighborhood window size; ; a value smaller than or equal to neighbors_N(ecotoner_settings).
migtype	A character string; one of get("migtypes", envir = etr_vars).
ecotoner_settings	An object of the class EcotonerSettings.
etband	The object of the ecotone transect according to index i that was returned by the function detect_ecotone_transects_from_searchpoint.
etmeasure	The object of the ecotone transect according to index i that is created by the function detect_ecotone_transects_from_searchpoint.
copy_FromMig1_TF	A logical value. If TRUE and migtype is not “AllMigration”, then output is copied from “AllMigration” instead of re-calculated.
do_figures	A logical value. If TRUE, then figures are generated and saved to disk.
...	Further arguments. Currently implemented are seed (to seed the random number generator), flag_bfig (character string to include in file names of figures), and dir_fig (character string of the path where figures are to be stored on disk).

Value

The object etmeasure with output of the call to calc_Danz2012_abruptness_2D based on doms, b, and migtype integrated.
