This function creates annual rasters of refugia for an ESM of interest, using a temporal threshold (where refugia conditions must be met for 50 or 95% of the year). The function also displays a progress bar.
Usage
build_refugia(
percentdays = abalone::percentdays,
esm = c("ens", "gfdltv", "hadtv", "ipsltv"),
yrst = 1990,
yrend = 2100,
persist_thresh = c(50, 95),
progress = TRUE,
save_path = NULL
)Arguments
- percentdays
R object. Dataframe. Defaults to
abalone::percentdays(i.e., example package dataset of % days of stress)- esm
Character. ESM model to use. Choose from
ens,gfdltv,hadtv,ipsltv.- yrst
Integer. Start year. Defaults to 1990.
- yrend
Integer. End year. Defaults to 2100.
- persist_thresh
Integer. Temporal threshold (%) used for defining annual refugia. Choose either 50 (liberal) or 95% (conservative).
- progress
Logical. Show progress bar? Default is TRUE.
- save_path
Character. Directory to save output to. Optional, set to NULL if not needed.
Value
Produces a terra::rast() object of binary refugia (0/1), for the ESM specified, for all years between yrst and yrend.
Examples
ens_refugia <- build_refugia(percentdays = abalone::percentdays,
esm = "ens", yrst = 1990, yrend = 2100, persist_thresh = 50, progress = FALSE,
save_path = NULL)
