locdir: local data directory

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

local data directory

Description

This can be used to set a 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 does not exist, tempdir() is used instead (with a warning, unless quiet=TRUE). If dir is NULL, locdir tries "C:/DWDdata", then "~/DWDdata". dir can also be set with options(rdwdlocdir="YOUR/PATH") thanks to the DEFAULT: getOption("rdwdlocdir")
file	Optional: path(s) at dir. DEFAULT: NULL
quiet	Logical: suppress tempdir warning? DEFAULT: FALSE through rdwdquiet()

Value

charstring (directory)
