Build rasters of persistent refugia

Source: R/build_persist.R
build_persist.Rd

This function creates a single raster of persistent refugia for an ESM of interest, over a user-specified time period.

Usage

build_persist(
  esm = c("ens", "gfdltv", "hadtv", "ipsltv"),
  yr_range = c(1990:2019),
  persist_thresh = c(50, 95),
  save_path = NULL
)

Arguments

esm

Character. ESM model to use. Choose from ens, gfdltv, hadtv, ipsltv.

yr_range

Vector of integers. Time period.

persist_thresh

Integer. Temporal threshold (%) used for defining annual refugia. Choose either 50 (liberal) or 95% (conservative).

save_path

Character. Directory to save output to. Optional, set to NULL if not needed.

Value

Produces a terra::rast() object of persistent refugia (%), for the ESM specified.

Examples

persist_refugia <- build_persist(esm = "ens", yr_range = 2070:2099,
persist_thresh = 50, save_path = NULL)
