temperature_max_wc: Calculate maximum temperature statistics

Description

This function allows to efficiently calculate maximum temperature statistics from Worldclim for polygons. For each polygon, the desired statistic/s (min, max, sum, mean, median, sd or var) is/are returned.

Usage

calc_temperature_max_wc(engine = "extract", stats = "mean")

Value

A function that returns an indicator tibble with maximum temperature statistics as variables and corresponding values as value.

Arguments

engine

The preferred processing functions from either one of "zonal", "extract" or "exactextract" as character.

stats

Function to be applied to compute statistics for polygons either single or multiple inputs as character. Supported statistics are: "mean", "median", "sd", "min", "max", "sum" "var".

Details

The required resources for this indicator are:

• maximum temperature layer from worldclim_max_temperature

# \dontshow{
mapme.biodiversity:::.copy_resource_dir(file.path(tempdir(), "mapme-data"))
