Unable to run shiny app, error: Error in library(dplyr) : there is no package called ‘dplyr’

What I think is going on:
I am using reconnect: deployApp, and within the app.r file, I call 4 libraries: shiny, dplyr, ggplot2, ggthemes. The app works locally. The issue appears to be that the libraries are not being loaded that the app relies on.

if your code includes an explicit library(dplyr) then it is odd that rsconnect is failing to identify that.
One way I could think that things could go wrong with , might be perhaps if you were avoiding using Rstudio's 'project' features. Is your app a project in Rstudio ?

Yes, app is a project in Rstudio, but I am going to try starting a new "shiny" project and see if that works. I worked through the diamonds example by starting a new project, and it worked.

Update: After creating a fresh install (and separating app into UI/server files), it's working on the server. Thanks all for your help. While I don't know why it did not initially work, starting anew made the difference.
