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).

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.

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

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.

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.

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.

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.

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.

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.

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.

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.
