Box uses file versioning, but the API does not explicitly provide version
numbers. These functions use modified_date as a proxy to determine a
version number (version_no), which you can use with box_dl() and
box_read().
box_version_history(file_id)
box_version_number(file_id)numeric or character, file ID at Box.
box_previous_versions()data.frame describing previous versions of file.
box_version()integer version number of most-recent version of file.
box_version_history(), previously called box_previous_versions(),
gets information on all previous versions of a file. If there are no
previous versions, this function returns NULL.
box_version_number() gets the version number of the most-recent version.
To access the Box version API itself, you can use box_version_api().
This function is a light wrapper of the
box.com API versions method.
