Functions for calculating energy barrier from landscapes

Description

Functions for calculating energy barrier from landscapes

Usage

calculate_barrier(l, ...)

## S3 method for class ''2d_landscape''
calculate_barrier(
  l,
  start_location_value,
  start_r,
  end_location_value,
  end_r,
  base = exp(1),
  ...
)

## S3 method for class ''3d_landscape''
calculate_barrier(
  l,
  start_location_value,
  start_r,
  end_location_value,
  end_r,
  Umax,
  expand = TRUE,
  omit_unstable = FALSE,
  base = exp(1),
  ...
)

## S3 method for class ''2d_landscape_batch''
calculate_barrier(
  l,
  bg = NULL,
  start_location_value,
  start_r,
  end_location_value,
  end_r,
  base = exp(1),
  ...
)

## S3 method for class ''3d_landscape_batch''
calculate_barrier(
  l,
  bg = NULL,
  start_location_value,
  start_r,
  end_location_value,
  end_r,
  Umax,
  expand = TRUE,
  omit_unstable = FALSE,
  base = exp(1),
  ...
)

Arguments

l	A landscape object.
...	Not in use.
start_location_value, end_location_value	The initial position (in value) for searching the start/end point.
start_r, end_r	The search radius (in L1 distance) for the start/end point.
base	The base of the log function.
Umax	The highest possible value of the potential function.
expand	If the values in the range all equal to Umax, expand the range or not?
omit_unstable	If a state is not stable (the "local minimum" overlaps with the saddle point), omit that state or not?
bg	A 2d_barrier_grid or 3d_barrier_grid object if you want to use different parameters for each condition. Otherwise NULL as default.

Value

A barrier object that contains the (batch) barrier calculation result(s).
