Here I use shiny to develop an app which can do the following:
- Perform sentiment analysis on words,
- Perform sentiment analysis at sentense level,
- Get sentiment across a document
- Creat word frequencies
- Create a word cloud
- Mark positive and negative lines within text
I use sentimentr, worldcloud, topicmodeller and tm packages for this analysis.
