setup_seafloor: setup_seafloor

In Allgeier-Lab/arrR: Individual-Based Simulation Model of Artifical Reefs in R

setup_seafloor

Description

Setup seafloor for model run.

Usage

setup_seafloor(
  dimensions,
  grain = 1,
  reef = NULL,
  starting_values,
  random = 0,
  verbose = TRUE
)

Arguments

dimensions	Vector with number of rows and columns (spatial dimensions).
grain	Double with size of cells in x- and y-direction (spatial grain).
reef	2-Column matrix with coordinates of artificial reefs.
starting_values	List with all starting value parameters.
random	Numeric to randomize input values.
verbose	If TRUE, progress reports are printed.

Details

Function to setup the seafloor. The center of the seafloor raster is always x,y (0,0). bg_biomass and ag_biomass values are in g dry weight. nutrients_pool and deritus_pool values are in g nutrients. If reef cells are present, the cells in the corresponding raster layer are idntified usinge the value one.

If random > 0, the stochasticity is added to all starting values using x * (1 +- random) as minimum and maximum values, respectively.

Value

data.frame

Examples

reef <- matrix(data = c(-1, 0, 0, 1, 1, 0, 0, -1, 0, 0),
ncol = 2, byrow = TRUE)

seafloor <- setup_seafloor(dimensions = c(50, 50), grain = 1,
reef = reef, starting_values = default_starting)
