VariableEnv: Use species-specific sets of environmental data for SDMs

In brshipley/megaSDM: Integrating Dispersal and Time-step Analyses into Species Distribution Models

Use species-specific sets of environmental data for SDMs

Description

Using different sets of environmental variables to model species distributions can help to make more informative species distribution models. This function allows for the modelling of each species based upon a unique subset of the environmental variables.

Usage

VariableEnv(occlist, bglist, env_vars, occ_output, bg_output)

Arguments

occlist	a list of .csv files, each containing the occurrence points of a given taxon. The files should be named the same as the taxon of interest (e.g.,: ".../Canis_lupus.csv").
bglist	a list of .csv files corresponding to the background points provided for each taxon. This list of files should be order in the same way as the files given by occlist.
env_vars	a vector containing the names of the environmental variables (must exactly match column names) to keep for each species as a character strings separated by commas. For example, c("Bio1,Bio3", "Bio1,Bio12"). Like above, this vector should be in the same order as the lists of species/background points.
occ_output	the directory where output occurrence files will be placed.
bg_output	the directory where output background files will be placed.

Value

Writes .csv files of species occurrences to the sub-directory given by the occ_output argument and .csv files of background points to the sub-directory given by the bg_output argument.
