vosonSML 0.29.4

Minor Changes

• Renamed bimodal networks to twomode.

vosonSML 0.29.3

Minor Changes

• Added output messages from supplemental functions such as AddText() and Graph(). Also improved consistency of output messages from Collect and Create functions.

Bug Fixes

• Added a fix reddit gsub locale error https://github.com/vosonlab/vosonSML/issues/21.
• Changed bimodal network hashtags to lowercase as filter terms when entered are converted to lowercase.
• Fixed errors thrown when removing terms from bimodal and semantic networks.
• Removed a duplicate GetVideoData() function call in AddVideoData.
• Fixed data type errors in AddText functions related to strict typing by dplyr::if_else function.

vosonSML 0.29.2

Minor Changes

• A feature was added to the youtube actor AddText function to redirect edges towards actors based on the presence of a screen name or @screen name that may be found at the beginning of a reply comment. Typically reply comments are directed towards a top-level comment, this instead captures when reply comments are directed to other commenters in the thread.

vosonSML 0.29.1

Minor Changes

• Changed youtube actor network identifiers to be their unique Channel ID instead of their screen names.
• Created the AddVideoData function to add collected video data to the youtube actor network. The main purpose of this function is to replace video identifiers with the Channel ID of the video publisher (actor) instead. To get the Channel ID of video publishers an additional API lookup for the videos in the network is required. Additional columns such as video Title, Description and Published time are also added to the network $edges dataframe as well as returned in their own dataframe called $videos.

vosonSML 0.29.0

Major Changes

• Created the AddText function to add collected text data to networks. This feature applies to activity and actor networks and will typically add a node attribute to activity networks and an edge attribute to actor networks. For example, this function will add the column vosonTxt_tweets containing tweet text to $nodes if passed an activity network, and to $edges if passed an actor network.
• Generation of igraph graph objects and subsequent writing to file has been removed from the Create function and placed in a new function Graph. This change abstracts the graph creation and makes it optional, but also allows supplemental network steps such as AddText to be performed prior to creating the final igraph object.

Minor Changes

• Removed writeToFile parameter from Create functions and added it to Graph.
• Removed weightEdges, textData and cleanText parameters from Create.actor.reddit. cleanText is now a parameter of AddText.activity.reddit and AddText.actor.reddit.
• Replaced AddTwitterUserData with AddUserData function that works similarly to AddText. This function currently only applies to twitter actor networks and will add, or download add if missing, user profile information to actors as node attributes.

vosonSML 0.28.1

Minor Changes

• Added activity network type for reddit. In the reddit activity network nodes are the thread posts and comments, edges represent where comments are directed in the threads.
• Added github dev version badge to README.

vosonSML 0.28.0

Major Changes

• Added new activity network type for twitter and youtube Create function. In this network nodes are the items collected such as tweets returned from a twitter search and comments posted to youtube videos. Edges represent the platform relationship between the tweets or comments.

vosonSML 0.27.3

Minor Changes

• Added a new twitter actor network edge type self-loop. This aims to facilitate the later addition of tweet text to the network graph for user tweets that have no ties to other users.

vosonSML 0.27.2

Minor Changes

• Added twitter interactive web authorization of an app as provided by rtweet::create_token. Method is used when only twitter app name and consumer keys are passed to Authenticate.twitter as parameters. e.g Authenticate("twitter", appName = "An App", apiKey = "xxxxxxxxxxxx", apiSecret = "xxxxxxxxxxxx"). A browser tab will open asking the user to authorize the app to their twitter account to complete authentication. This is using twitters Application-user authentication: OAuth 1a (access token for user context) method.
• It is suspected that Reddit is rate-limiting some generic R UA strings. So a User-Agent string is now set for underlaying R Collect functions (e.g file) via the HTTPUserAgent option. It is temporarily set to package name and current version number for Collect e.g vosonSML v.0.27.2 (R Package).
• Removed hex sticker (and favicons for pkgdown site).

vosonSML 0.27.1

Bug Fixes

• Fixed a bug in Create.semantic.twitter in which a sum operation calculating edge weights would set NA values for all edges due to NA values present in the hashtag fields. This occurs when there are tweets with no hashtags in the twitter collection and is now checked.
• Some UTF encoding issues in Create.semantic.twitter were also fixed.

Minor Changes

• Added ‘#’ to hashtags and ‘@’ to mentions in twitter semantic network to differentiate between hashtags, mentions and common terms.

vosonSML 0.27.0

Bug Fixes

• Fixed a bug in Collect.twitter in which any additional twitter API parameters e.g lang or until were not being passed properly to rtweet::search_tweets. This resulted in the additional parameters being ignored.

Major Changes

• Removed the SaveCredential and LoadCredential functions, as well as the useCachedToken parameter for Authenticate.twitter. These were simply calling the saveRDS and readRDS functions and not performing any additional processing. Using saveRDS and readRDS directly to save and load an Authenticate credential object to file is simpler.
• Changed the way that the cleanText parameter works in Create.actor.reddit so that it is more permissive. Addresses encoding issues with apostrophes and pound symbols and removes unicode characters not permitted by the XML 1.0 standard as used in graphml files. This is best effort and does not resolve all reddit text encoding issues.

Minor Changes

• Added Collect.twitter summary information that includes the earliest (min) and latest (max) tweet status_id collected with timestamp. The status_id values can be used to frame subsequent collections as since_id or max_id parameter values. If the until date parameter was used the timestamp can also be used as a quick confirmation.
• Added elapsed time output to the Collect method.

vosonSML 0.26.3

Bug Fixes

• Fixed bugs in Create.actor.reddit that were incorrectly creating edges between top-level commentors and thread authors from different threads. These bugs were only observable in when collecting multiple reddit threads.

Minor Changes

• Improved output for reddit collection. Removed the progress bar and added a table of results summarising the number of comments collected for each thread.
• Added to twitter collection output the users twitter API reset time.

vosonSML 0.26.2

Bug Fixes

• Fixed a bug in Create.actor.twitter and Create.bimodal.twitter in which the vertices dataframe provided to the graph_from_data_frame function as a contained duplicate names raising an error.

Major Changes

• Revised and updated roxygen documentation and examples for all package functions.
• Updated all Authenticate, Collect and Create S3 methods to implement function routing based on object class names.

Minor Changes

• Created a pkgdown web site for github hosted package documentation.
• Created a new hex sticker logo.

vosonSML 0.25.0

Major Changes

• Replaced the twitteR twitter collection implementation with the rtweet package.
• A users twitter authentication token can now be cached in the .twitter_oauth_token file and used for subsequent twitter API requests without re-authentication. A new authentication token can be cached by deleting this file and using the re-using the parameter useCachedToken = TRUE.
