THIS FUNCTION IS CURRENTLY DISABLED. Takes an emtools.species object and environmental layers, and constructs a hypervolume using the R package hypervolume

Description

THIS FUNCTION IS CURRENTLY DISABLED. Takes an emtools.species object and environmental layers, and constructs a hypervolume using the R package hypervolume

Usage

enmtools.hypervolume(
  species,
  env,
  samples.per.point = 10,
  reduction.factor = 0.1,
  method = "gaussian",
  verbose = FALSE,
  clamp = TRUE,
  ...
)

Arguments

species	An enmtools.species object
env	A stack of environmental rasters
samples.per.point	To be passed to hypervolume_gaussian
reduction.factor	To be passed to hypervolume_project
method	Method for constructing hypervolumes, defaults to "gaussian"
verbose	Controls printing of various messages progress reports. Defaults to FALSE.
clamp	When set to TRUE, clamps the environmental layers so that predictions made outside the min/max of the training data for each predictor are set to the value for the min/max for that predictor. Prevents the model from extrapolating beyond the min/max bounds of the predictor space the model was trained in, although there could still be projections outside the multivariate training space if predictors are strongly correlated.
...	Extra parameters to be passed to hypervolume_gaussian

Value

An enmtools hypvervolume object containing a hypervolume object, a raster of suitability scores, the species name, and the occurrence data frame.

Examples

#install.extras(repos='http://cran.us.r-project.org')
env <- euro.worldclim[[c(1,8,12,17)]]
if(requireNamespace("hypervolume", quietly = TRUE)) {
    monticola.hv <- enmtools.hypervolume(iberolacerta.clade$species$monticola, env = env)
}
