I'm attempting to create a drill-down dashboard using Shiny. I've been reading multiple content on the subject, and found this question and answer to be most relevant:
Edgar Ruiz's answers point to two articles:
, which I've thoroughly worked through and tried to implement on my own code. The Flights Dashboard https://edgarruiz.shinyapps.io/flights-dashboard/ is the example used in the articles, and I've copied the full example code of the local app https://github.com/sol-eng/db-dashboard/blob/master/local/local_app.R and tried to run it from my Rstudio.
When running both my own script and the example code (hyperlink above), I get an error:
"Error: col_plot is not defined ReferenceError: col_plot is not defined"
Is there somthing I'm missing perhaps? Alternatively, is there a better way to do drill-downs to be aware of?
