content_dir | R Documentation |
A configurable default location for persistent data storage
content_dir(dir = Sys.getenv("CONTENTID_HOME", tools::R_user_dir("contentid")))
dir |
directory to be used as the home directory |
This function is intended to be called internally with no
arguments. It will use the directory set by the system environmental
variable CONTENTID_HOME, if set. Otherwise, it will use the default
location returned by tools::R_user_dir for the application,
contentid
. Unlike rappdirs function, this function will also
create the directory if it does not yet exist.
## example using temporary storage:
Sys.setenv(CONTENTID_HOME=tempdir())
content_dir()
## clean up
Sys.unsetenv("CONTENTID_HOME")
## Or explicitly with an argument:
content_dir(tempdir())
