#' Get the available datasets.
#'
#' List the datasets available in pastclim, which can be passed to functions
#' in `pastclim` as values for the parameter `dataset`. Most functions can also be
#' used on custom datasets by setting `dataset="custom"`
#'
#' This function provides a user-friendly list, summarising the many datasets
#' available from WorldClim. A comprehensive list of all available datasets
#' can be obtained with [list_available_datasets].
#'
#' @returns a character vector of the available datasets
#' @export
