tdf2swd {tenm}

Temporal data.frame to Samples With Data format

Description

Converts a temporal data.frame to Samples With Data (SWD) table for use with other modeling platforms such as MaxEnt.

Usage

tdf2swd(this_species, sp_name = "sp")

Arguments

this_species

An object of class sp.temporal.env (see ex_by_date ) or sp.temporal.bg (see bg_by_date).

sp_name

Character vector specifying the species name.

Value

A data.frame formatted as Samples With Data (SWD) table.

Examples

data("abronia")
tempora_layers_dir <- system.file("extdata/bio",package = "tenm")
