locdir: local data directory

In rdwd: Select and Download Climate Data from 'DWD' (German Weather Service)

local data directory

Description

Get the directory for DWD data across projects, thus avoiding multiple downloads of the same file.
Set the default for all subsequent calls with options(rdwdlocdir="YOUR/PATH").
You could add this to your .Rprofile file e.g. via usethis::edit_r_profile()

Usage

locdir(dir = getOption("rdwdlocdir"), file = NULL, quiet = rdwdquiet())

Arguments

dir	Path to data directory. If dir is NULL, locdir tries "C:/DWDdata", then "~/DWDdata", then tools::R_user_dir⁠("rdwd", which="cache")⁠. dir can also be set with options(rdwdlocdir="YOUR/PATH") thanks to the DEFAULT: base::getOption("rdwdlocdir")
file	Optional: path(s) at dir. DEFAULT: NULL
quiet	Ignored since version 1.9.4 (2025-10-20). DEFAULT: FALSE through rdwdquiet()

Value

charstring (directory)
