Interactively offers the user to set up the default root path.
# S3 method for default
setupCacheRootPath(defaultPath=NULL, ...)
Returns (invisibly) the root path,
or NULL
if running a non-interactive session.
Default root path to set.
Not used.
Henrik Bengtsson
If the cache root path is already set, it is used and nothing is done.
If the "default" root path (defaultPath
) exists, it is used,
otherwise, if running interactively, the user is asked to approve
the usage (and creation) of the default root path.
In all other cases, the cache root path is set to a session-specific
temporary directory.
Internally, setCacheRootPath
() is used to set the cache root path.
The interactive
() function is used to test whether R is
running interactively or not.
