Shinyapps.io Error with trying to use NGLVieweR package

Hi there,
I'm having issues deploying my code on this website. When I try to run it I get the error: exit code 1. I checked the logs and it says that: Error in install.packages("NGLVieweR") : unable to install packages

I know that this package exists as I'm using it on my local computer right now but I'm new to this whole thing and really don't know how to resolve this issue. Any suggestions would be incredibly helpful!
