I'd like to know how I can get information about sharing posts on Facebook, such as name and id of users, and share date and time.
In the RFacebook package, you can get the same information but refer to tastings and comments, not shares.
On Facebook this type of data is public if you inform the publication you are interested in.
First you need to get the posts of the person you want by using getPage to access timeline , after you get the ID of the post you want to use Object SharedPosts directly in API HTTP do facebook , unfortunately RFacebook does not yet support this objeto .
GET /v2.5/{object-id}/sharedposts HTTP/1.1
Host: graph.facebook.com
Being ObjectID o post you want to get sharing information.
For more information I suggest you consult the address: link
