sim.env
allows to simulate environmental fields.
Usage
sim.env(
grid,
nt = 9,
rho_t = 0.85,
sd = 2,
h = 0.2,
nu = 2,
rho_s = NULL,
delta = 0.1,
zrange = c(20, 28),
matern = TRUE,
diagonal = FALSE,
verbose = TRUE
)
Arguments
- grid
a grid.
- nt
number of environmental fields. Default:
1
.- rho_t
autocorrelation coefficient of temporal autocorrelation for environmental fields. Default:
0.85
.- sd
standard deviation for simulation of environmental fields. Default:
2
.- h
parameter of the matern covariance structure. Default:
0.2
.- nu
parameter of the matern covariance structure. Default:
2
.- rho_s
parameter of the matern covariance structure. Default:
0.8
.- delta
parameter of the matern covariance structure. Default:
0.1
.- zrange
range of the environmental covariate. Default:
c(20, 28)
.- matern
logical; if
TRUE
(default), matern covariance structure is used for simulation of environmental fields.- diagonal
logical; if
TRUE
, diagonal neighbours are considered in neighbouring structure. Default:FALSE
.- verbose
If
TRUE
, print information to console. Default:TRUE
