Standard local checkout location for extra registration directories
local_reg_dir_for_url(url = NULL)path(s) containing registrations on disk.
Character vector containing a url. When url=NULL defaults
to giving the base path.
When called without any argument returns the root directory that
will be inspected for extra registrations. You can put a sub-folder
yourself there manually and then call add_reg_folders, but you are much
better off in general using download_reg_repo to install from
a github repository such as this one of ours:.
jefferislab/BridgingRegistrations
Note that this folder will always be the same place on a machine i.e. this
defines a consistent, persistent location on disk to store data across
sessions. You can modify the location of this folder by editing the
R_USER_DATA_DIR environment variable. While this is not recommended
on a personal machine, it may be necessary on a server. See
rappdirs::user_data_dir for details.
When called with a url, a SHA1 hash will be calculated for the URL and appended to the basepath. This should ensure that locations derived from different URLs do not clash.
