In ELAplus: Energy Landscape Analysis for Ecological Communities

Energy landscape analysis in parallel mode

Description

Identifying stable states and tipping points.

This function estimates stable states by repeated steepest-descent searches SSestimate and then checks tipping points between all pairs of stable states using FindingTippingpoint_cpp. The result is summarized and converted by elaconvert into a list of stable state IDs, their energies, tipping point IDs, and tipping energies.

Usage

ELA(
  sa = sa,
  env = NULL,
  SS.itr = 20000,
  FindingTip.itr = 10000,
  threads = 1,
  reporting = TRUE,
  fork = TRUE
)

Arguments

sa	output of runSA function.
env	vector of environmental factors for specifying a single environmental condition (optional).
SS.itr	number of iterations of the process to identify the stable states.
FindingTip.itr	number of iterations of the process to identify the tipping points.
threads	number of cores (threads) used for calculation.
reporting	enable/disable the reporting function.
fork	logical; if TRUE and threads > 1, a cluster is created internally for parallel execution.

Value

A list returned by elaconvert: (1) stable state IDs, (2) stable state energies, (3) tipping point ID matrix/list, and (4) tipping energies matrix/list.
