Usage

# S3 method for `2d_Isingland`
calculate_barrier(l, ...)

# S3 method for `2d_Isingland_matrix`
calculate_barrier(l, ...)

# S3 method for barrier_2d_Isingland
print(x, simplify = FALSE, ...)

# S3 method for barrier_2d_Isingland
summary(object, ...)

# S3 method for barrier_2d_Isingland_matrix
summary(object, ...)

Arguments

l

An Isingland object constructed with make_2d_Isingland() or make_2d_Isingland_matrix().

...

Not in use.

x

a result of the default method of summary().

simplify

Print a simplified version of the output? Default is FALSE.

object

an object for which a summary is desired.

Value

A barrier_Isingland object that contains the following components:

  • shape A character describing the shape of the landscape.

  • local_min_start,local_min_end,saddle_point The positions of the two local minimums and the saddle point, described each by a list containing:

    • U The potential value.

    • location

      • x_index The row index in get_dist(l).

      • x_value The number of active nodes.

  • delta_U_start,delta_U_end The barrier heights for both sides.

Functions

  • summary(barrier_2d_Isingland): Return a vector of barrier heights.

  • summary(barrier_2d_Isingland_matrix): Return a tibble of barrier heights and conditions.
