Description Usage Arguments Details Value Author(s) See Also Examples

facebook.object.likes pulls information about the likes from a list of Facebook IDs and/or names of users or pages and push them into a FacebookMixedCollection-class instance.

1 2	facebook.object.likes(id, token = NULL, parameters = list(), n = getOption("facebook.maxitems"), .progress = create_progress_bar())

`id`	An existing `FacebookUsersCollection` or `FacebookPagesCollection`
`token`	Either a temporary access token created at https://developers.facebook.com/tools/explorer or the OAuth token created with `fbOAuth`. If `NULL` and `id` is a Collection, get that one instead. Otherwise, no query is performed to the Facebook Graph API and an empty Collection is returned
`parameters`	A list of parameters to be added to the Facebook Graph API query. For more information on the accepted parameters, see: https://developers.facebook.com/docs/graph-api/using-graph-api
`n`	An integer value with the maximum number of participants to be pulled for each conversation in `id`. It can be set to `Inf` to pull out any participant of a given conversation and assumes the default value to `facebook.maxitems` global option if missing.
`.progress`	progress_bar object as defined in the plyr package. By default the `none` progress bar is used, which prints nothing to the console.

This function requires the use of a OAuth token with user_likes permission granted. After the introduction of version 2.0 of the Graph API, only likes from users who are using the application that you used to generate the token to query the API will be returned.

Only the id and the type is returned in a mixed collection. Then, a proper collection for each type must be built accordingly.

A collection of mixed likes in a FacebookMixedCollection-class object with the id and the type for each element included.
