Hello,
I hope this is the correct place to post about this. I'm currently reading the Shiny tutorial to refresh my memory and I noticed that in Lesson 5, chapter "Loading files and file paths" the tutorial talks about server.R instead of app.R, that is used in the rest of the tutorial. I guess this part of the tutorial was not updated when Shiny moved from separate ui.R and server.R files to a single app.R file.
Just wanted to point this out so it can be fixed to avoid potential confusion with new readers. By the way, the Shiny tutorial is great, and serves as a very fast way to remind me of the core concepts!
