Usage

datacube_aggregation(
  input_path,
  output_filename = "",
  fun = sum,
  cores = 1,
  ...
)

input_path: Path to the datasetcube
output_filename: Path to the output file
fun: Function to be applied to the datasetcube (default is sum). The function must be a function that takes a vector as input and returns a single value. The main functions to be used are: Sum, Mean, Min, Max, First and Last. For last, use dplyr::last. To use customized function say, for example "min", you could use use the format fun = \(x) min(x). See terra::tapp() for more information.
cores: Number of cores to use for the aggregation. Default is 1. See terra::tapp() for more information. See terra::tapp() for more information.
...: Additional arguments to pass to names_to_date()

A raster object with the aggregated data

datacube_aggregation() aggregates a datacube by a given function. The function will be applied to each day of the datacube.
