VOSONDash 0.4.4

Minor Changes:

• Changed the required package check to be more efficient by calling required() instead of installed.packages().
• Changed the app startup messages to use message() instead of cat() so if desired they can be suppressed.
• Added pkgStartupMsgs parameter to runVOSONDash() to hide the app’s required package startup messages.
• Added optional isLocal parameter to runVOSONDash() to manually set local or server flag if desired. If not set app will detect if it is running in server mode.
• Disabled the loading and saving of keys and tokens in server mode.
• Added a tooltip to Create Web Auth Token to add some further information on process and note.

VOSONDash 0.4.3

Minor Changes:

• Changed the node size controls in Network Graphs to be based on normalized continuous values.
• Moved the calculation of network metrics to the getNetworkMetrics() package function.
• Demonstration data select box now hidden when another data source is loaded.
• Abbreviated long name layouts in the Graph layout control.
• Added tooltips to various interface controls using the popper.js javascript library (v1.14.3). Documentation at https://getbootstrap.com/docs/4.1/components/popovers/ and https://popper.js.org.

VOSONDash 0.4.2

Bug Fixes:

• Fixed problem with visNetwork graphs rendering slightly off the canvas.

Major Changes:

• VOSONDash Shiny app has been re-structured into an R package. Have started moving some of the ‘business logic’ away from the app server and into the general package.
• Social Media API keys are no longer saved to the users working directory. API keys and tokens are now saved to files in the users home directory as specified by the system environment variable HOME. This location can be found in the VOSONDash start up information, in the apps API Keys tab or by using the following R function in RStudio: Sys.getenv("HOME"). The keys and tokens files are named vosondash_keys.rds and vosondash_tokens.rds respectively.
• Twitter no longer creates an API authentication token for each twitter collection. Instead twitter tokens are now created and managed in the API Keys tab and should be saved and re-used.
• A twitter web authorization token can now be created and used for API access without the need for a Developer account. This still requires a twitter app and Consumer API keys but means if a user has access to these that the user can authorize the twitter app against their account and use VOSONDash to perform twitter collections. Using this token API rate-limiting will be applied to the users account not the app. Twitter refers to this method of authentication as ‘Application-user authentication: OAuth 1a (access token for user context)’. This feature uses the rtweet packages interactive web authorization as implemented by the rtweet::create_token function. As stated above once a token has been created it should be saved and re-used.

Minor Changes:

• Demonstration data has been included in the package and is accessible by a new selection box below the graphml file loader in Network Graphs. If there is a file with the same name as the demonstration graphml file but with an additional ‘.txt’ extension in the packages demonstration data folder it will be loaded as the graph description.
• Added graph summary information for Network Graphs plots as an overlay in the bottom left corner.
• Added a select box in the top right corner of the graph plots that the user can use to select the render plot height in pixels.
• Changed selected row and vertex highlighting colors in graph data table and plot.
• Removed visNetwork plot navigation controls.
• Removed D3 network plots for the time being.
• NRC sentiment analysis plots have been re-worked and now split into the 8 emotions, measured and sorted as the proportion of the total of the emotions in the text and the valence which is the measure of how positive or negative the text is.
• The All categories plot has now been removed from text analysis when single categories are chosen or combined. In that particular use-case the plots are the same. It will only be shown when the All value in the sub-categories select box is selected.
• Removed keys fields from Collect twitter and it now displays selected auth token.
• Variable naming changes and a lot of code re-structuring and refactoring.
