TwitterShinyApp

Interactive Shiny App developed by Carlo R. M. A. Santagiustina for downloading and processing data from Twitter's Search API using R and the following R libraries (shiny,Matrix,rjson,jsonlite,httr,rvest,tidyverse,shinyjs,DT,openxlsx,quanteda,rtweet,stringr,tibble,rtweet,shinythemes,ggplot2,quanteda). You can use the TwitterShinyApp to download up to 18000 tweets every 15min from the Twitter Search API (get-search-tweets endpoint), by keyword and/or by geocode (for more info on the endpoint see: https://developer.twitter.com/en/docs/tweets/search/api-reference/get-search-tweets.html). The TwitterShinyApp also allows you to analyse and process through a user friendly interface downloaded tweets. Implemented functionalities include:

• Summary statistics by variable (column);
• Ngrams and term/pattern context analysis;
• Time series of tweets counts for multiple time frequencies (weeks, days, hours, mins, secs);
• Textual data cleaning (text and user description);
• Extraction of URLs;
• Extraction of emoticones;
• Extraction of hashtags (#), usertags (@) and fintags ($);
• Hashtags and usertags frequency analysis and wordclouds for most frequent hashtags/usertags;
• Hashtag and usertag cooccurrence network (construction + visualization) for most frequent hashtags/usertags;

To run the app locally:

1. Download the app - nocredentials.R file;
2. Install R version 3.5 (or later) and RStudio;
