I'm new to Shiny and I was just trying to see what's the result gonna look like and test out different data sets. I entered the code provided by Diego Lescano, you can find the full script here, http://datascienceplus.com/how-to-create-a-twitter-sentiment-analysis-using-r-and-shiny/
Everything ran through smoothly, however I wasn't able to see the final graph when I tried to knit. Instead, I received the following warning
output file: Final_Project.knit.md
Error: path for html_dependency not provided
Execution halted
I tried to knit to pdf and word as well, it all failed. Here's what my output looked like
output: html_document: default
