ask for hepl about Rshiny

I can run well locally, but uploading to the website :


I don't have a server. I want to host it

do you mean ?
If so the advice here : Chapter 9 Troubleshooting | user guide (
is to use either rsconnect::showLogs() to get logs for your app
or visiting the dashboard and looking at the logs in your Application view.

Thank u so much. It is related to UTF-8 format.
I have use tidyverse to deal with it. doesn't yet support R 4.1.2 I think the latest is R 4.1.0

Anyway your issue I think related to the character encoding of your script file(s). I believe UTF-8 is preferred
