Error - Application failed to start

[KrisPad]

I'm reading a text file ( i.e. ,txt file of numeric data) -- using read.table and naming the result 'housescal' . However 'shinyapps.io' fails to find the file 'housescal' . Everything works locally. I read the file within the renderPlot statement . What is going on here?

Here is the log:

Are you uploading the file along your app's code when you deploy the app? Other than this, I think it would be impossible for us to know what is going on without seen the app's code.

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at these resources, to see how to create one for a shiny app

Shiny debugging and reprex guide

Shiny issues can be challenging to resolve relative to other problems with your code or statistical methods. Shiny apps are often large, complex projects with interacting files. When seeking help from others it is considered polite to: First, do your best to work through RStudio's debugging tools to diagnose your issue on your own. Often those shiny logs and tracebacks are useful to others trying to help out. Second, strive to minimize the effort required to replicate your issue. You can do this with a reproducible example ("reprex"). Shiny Debugging Errors in Shiny code can be difficult to track down. If you don't know where your problem is coming from, you can track it down with some o…
