FacebookConversationsCollection: Build a collection of Facebook inbox conversations

In facebook.S4: Access to Facebook API V2 via a Set of S4 Classes

Description

Connect to Facebook Graph API, get information from a list of inbox conversations and build a FacebookConversationsCollection-class instance.

Usage

FacebookConversationsCollection(id, token = NULL, parameters = list(),
  fields = c("id", "snippet", "updated_time", "message_count"),
  n = getOption("facebook.maxitems"), metadata = FALSE,
  .progress = create_progress_bar())

Arguments

id	A character vector or a comma-delimited string of IDs or an existing Facebook Collection of any of the supported types (see below).
token	Either a temporary access token created at https://developers.facebook.com/tools/explorer or the OAuth token created with fbOAuth. If token NULL and id is a collection, use the token of the source collection. 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.
fields	A character vector with the fields to get for each id. If no value for a given field is found, it will be set to NULL.
n	If id is an iterable collection, then n is the maximum number of conversations to be pulled for each element of the source collection in id. It can be set to Inf to pull out any available conversation and assumes the default value from the value of facebook.maxitems global option if missing. If id is not a collection or cannot be iterated, the parameter is ignored.
metadata	If set to TRUE, the metadata for each ID is pulled with the data and the type slot is fed accordingly. Please note that setting this to TRUE could considerably slow down the execution time, as more queries are needed.
.progress	progress_bar object as defined in the plyr package. By default the none progress bar is used, which prints nothing to the console. See create_progress_bar for details.

Details

FacebookConversationsCollection is the constructor for the FacebookConversationsCollection-class. It returns data about inbox conversations of users or pages but doesn't return lists of messages or users involved.

A FacebookMessagesCollection-class can be built on top to pull out the messages of each conversation.

Value

A collection of conversations in a FacebookConversationsCollection-class object.

Nesting fields

Due to the network-graph nature of Facebook data model, you can specify fields details for each field nesting .fields() clauses.

For example, if you need only id and source for the cover field, this is valid among others: cover.fields(id,source).

Following the same philosophy, if you need only id and name for the from node you can use from.fields(id,name).

Valid sources

Instead of a character vector, one of these collections can also be passed as parameter in id:

• FacebookPagesCollection-class will build a collection with all the inbox conversations to pages of the source collection. A page access token with read_page_mailboxes is needed to read the related mailboxes.

• FacebookUsersCollection-class will build a collection with all the conversations that person is involved with if they are a developer of the application making the request. A user access token with read_mailbox is needed to perform this action.

• FacebookMixedCollection-class will build a collection with all the conversations, filtering only to the user and page in the source collection.
