R Documentation

rcpp_move_behav

Description

Rcpp simulate movement (behav).

Usage

rcpp_move_behav(
  fishpop,
  fishpop_attr,
  move_mean,
  move_sd,
  move_reef,
  move_border,
  move_return,
  max_dist,
  coords_reef,
  extent,
  dimensions
)

Arguments

`fishpop`	Matrix with fishpop values.
`fishpop_attr`	Matrix with id and threshold of pop_reserves_max.
`move_mean`, `move_sd`	Double with mean movement parameter.
`move_reef`	Double with mean movement distance when sheltering at reef.
`move_border`	Double with movement distance that surrounds reef cell border.
`move_return`	Double with mean movement distance when returning to reef.
`max_dist`	Maximum distance an individual can move.
`coords_reef`	Matrix with ID and coords of reef cells.
`extent`	Vector with extent (xmin,xmax,ymin,ymax).
`dimensions`	Vector with dimensions (nrow, ncol).

Details

Fish individuals move based on how much nutrients they have stored in their reserves. There are three different movement states.

If reserves are above a certain threshold, individuals either shelter at reef cells (state 1) or move back towards reef cells (state 2). If reserves are not above the threshold, individuals move randomly across the seafloor to forage (state 3).
