load_occ: Load occurrence data

Description

Load occurrence data from CSV file to perform modelling, ensemble_modelling or stack_modelling.

Usage

load_occ(path = getwd(), Env, file = NULL, ..., Xcol = "Longitude",
  Ycol = "Latitude", Spcol = NULL, GeoRes = TRUE,
  reso = max(res(Env@layers[[1]])), verbose = TRUE, GUI = FALSE)

Arguments

path

character. Path to the directory that contains the occurrence table.

Env

raster stack. Environmental variables in the form of a raster stack used to perform spatial thinning (can be the result of the load_var function).
