Shiny app 'Selected file too large' in RStudio

[lc201203]

I have built a Shiny app that exceeds the 5 MB source editor limitation in RStudio and haven't been able to find much information already out there. The vast majority of the code in my app is dynamic UI elements (namely a lot of renderUI() functions) that respond to user input and update the page accordingly. As far as I know, there is not a way to "function-ize" UI elements within Shiny the way you would be able to in something like AngularJS in order to reduce the file size. What I am wondering is if there is any way to modify the file size limitation in RStudio or if I will have to move to a text editor like Notepad++ to continue working on this app?

Try this: 
options(shiny.maxRequestSize=300*1024^2)   # change the number if needed

You absolutely can use functions in both UI and server side of Shiny apps. In this case I suspect you want to use modules.

5mb is a truly astounding amount of source code for a single app. Would you be able to share what you are doing and what some of you renderUI looks like?
