Return the Weatherfunctions data directory path and optionally create it.

The directory is not created automatically on package load to avoid CRAN side effects. Users can call this helper explicitly or opt into automatic creation by setting `options(weatherfunctions.auto_setup = TRUE)` before loading the package.

Usage

weatherfunctions_data_dir(create = FALSE, ask = interactive())

Arguments

create

Logical; create the directory if it does not exist.

ask

Logical; when interactive and creation is requested, ask before writing to the file system.

Value

A character string with the path used for local cache files.
