getShares function

Extract list of users who publicly shared a public Facebook post

getShares retrieves a list of posts that correspond to shares of a post on a public Facebook page. Only public posts by users who have granted authorization to the app used to authenticate.

getShares(post, token, n = 100)

Arguments

• post: A post ID
• token: Either a temporary access token created at https://developers.facebook.com/tools/explorer or the OAuth token created with fbOAuth.
• n: numeric, maximum number of shares to return.

Details

getShares returns a data frame with four variables: from_name

(the name of the user who shared the post), from_id (the ID of the user who shared the post), shared_time (the time at which the post was shared), and id (the ID of the new post).

For more information on why not all shared posts are returned, see here: https://developers.facebook.com/bugs/1404733043148335/
