Problem Deploying on Shinyapps.io plot.new has not been called yet

[jbhill]

Hi all,

Relatively new to Shiny, but have deployed a couple of apps before this, with no problem. I've been using relative filepaths, which is the only answer I've been able to find on the forums. Here is my log info:

I've tried reordering the libraries, in case it was a masking issue, but have not been able to figure this out. Any help or direction at all would be useful.

One other thing I might mention is that I'm using a .shp file and combining that with some API data on the back end. Everything works well locally, but no joy on publishing to shinyapps.io.

Thanks.

I figured this out - I was relying on the box() function, used in the shinydashboard library, but without meaning to or calling the shinydashboard library. Because there is a box() function in the graphics library, it was attempting to call a plot instead of providing a box around my sliders.

Basically, a bonehead mistake, but an easy one to make if you're switching between base shiny and shinydashboards.
