In ElliotDovers/scampr: Spatially Correlated, Approximate Modelling of Point patterns in R

Perform simulations from a scampr model to calculate global envelopes for the inhomogeneous K function

Description

Perform simulations from a scampr model to calculate global envelopes for the inhomogeneous K function

Usage

kfunc_envelopes(
  model,
  conf.level = 0.95,
  nsims = 100,
  Kfun.correction = c("border", "bord.modif", "isotropic", "translate"),
  return.data = F,
  spatstat.win,
  dists = NULL
)

Arguments

model	a scampr model object
conf.level	a numeric between 0 and 1 indicating the confidence level of the global envelope test
nsims	an integer describing the number of simulations to conduct
Kfun.correction	a character string describing the correction type to be used. See spatstat::Kinhom() for details.
return.data	a logical indicating whether to return the observed and simulated data
spatstat.win	Optionally, a spatstat window object.
dists	a vector of values for the distances at which the inhomogeneous K function should be evaluated. Not normally given by the user; spatstat provides a sensible default.

Value

Optionally, a list of the observed and simulated K functions - see GET::create_curve_set(). Results are plotted.

Examples

# Get the data
dat <- scampr::gorillas
dat$elev <- scale(dat$elevation)
mod <- scampr(pres ~ elev, dat, model.type = "PO", include.sre = F)
kfunc_envelopes(mod)
