spm_as_boundary: Create a sspm_boundary object

In pedersen-fisheries-lab/spaspm: Spatial Surplus Production Model Framework for Northern Shrimp Populations

Create a sspm_boundary object

Description

Create a sspm_boundary object. A boundary object serves as a basis to encode the spatial extent of the model.

Usage

spm_as_boundary(
  boundaries,
  boundary,
  patches = NULL,
  points = NULL,
  boundary_area = NULL,
  patch_area = NULL
)

## S4 method for signature 'missing,ANY,ANY,ANY'
spm_as_boundary(
  boundaries,
  boundary,
  patches = NULL,
  points = NULL,
  boundary_area = NULL,
  patch_area = NULL
)

## S4 method for signature 'ANY,missing,ANY,ANY'
spm_as_boundary(
  boundaries,
  boundary,
  patches = NULL,
  points = NULL,
  boundary_area = NULL,
  patch_area = NULL
)

## S4 method for signature 'sf,character,missing,missing'
spm_as_boundary(
  boundaries,
  boundary,
  patches = NULL,
  points = NULL,
  boundary_area = NULL,
  patch_area = NULL
)

## S4 method for signature 'sf,character,ANY,ANY'
spm_as_boundary(
  boundaries,
  boundary,
  patches = NULL,
  points = NULL,
  boundary_area = NULL,
  patch_area = NULL
)

Arguments

boundaries	[sf] The sf object to cast.
boundary	[character] The column that contains the possible subdivisions of the boundaries.
patches	[sf] Patches resulting from discretization.
points	[sf] Sample points used for discretization.
boundary_area	[character] The column that contains the area of the subdivisions (optional).
patch_area	[character] The column that contains the area of the patches (optional).

Value

An object of class sspm_boundary or sspm_discrete_boundary.

Examples

sfa_boundaries
bounds <- spm_as_boundary(boundaries = sfa_boundaries,
                          boundary = "sfa")
plot(bounds)
