I have a Shiny appl and would like to pass console messages to the app so the end user has an idea of what's happening with long running processes. Is there a way to pass what I see in the console to the end user? For example, when I export to SQL server I can see the batches being processed in the console, when I run machine learning models I can see iterations of the learning process, etc. I understand I can use withProgress if I know something about the dataframe, but this is not sufficient since iterations and dataframe information is not available to accurately estimate progress. Bottom line, does anyone know of a function or way to simply pass the messages in the console to a Shiny App.
Thank you!
