SWD to csv

Save an SWD object as csv file.

Usage

swd2csv(swd, file_name)

Arguments

swd

SWD object.

file_name

character. The name of the file in which to save the object, see details.

Details

• The file_name argument should include the extension (i.e. my_file.csv).

• If file_name is a single name the function saves the presence absence/background locations in a single file, adding the column pa with 1s for presence and 0s for absence/background locations. If file_name is a vector with two names, it saves the object in two files: the first name is used for the presence locations and the second for the absence/background locations.

# Acquire environmental variables
files <- list.files(path = file.path(system.file(package = "dismo"), "ex"),
                    pattern = "grd",
                    full.names = TRUE)

predictors <- terra::rast(files)

# Prepare presence and background locations
p_coords <- virtualSp$presence
bg_coords <- virtualSp$background

# Create SWD object
data <- prepareSWD(species = "Virtual species",
                   p = p_coords,
                   a = bg_coords,
                   env = predictors,
                   categorical = "biome")
