displaying TRUE when shiny files are split into different folders

Question

I have a shiny app using the package shinydashboard.

At first, I had all the files as 3 files - global.R, server.R, ui.R.

As files got bigger and messy, I took out the codes for each menus, and placed them in a separate folder. (splitting shiny files - http://shiny.rstudio.com/articles/scoping.html)

everything works, but there's something annoying happening - it displays 'TRUE' at the bottom of the ui of the menus I split into separate folder.

If everything is just in one big file, it doesn't display TRUE.

anyone know why this is happening?

functionally, everything is same.

Answer 1

What's happening is that source returns a list with 2 things inside: value which is the actual R code inside, and visible which is whether or not the code returned visibly or invisibly. The TRUE you are seeing is a reflection of the fact that the code returned visibly.

What you want to do is include the value of that list. So instead of

source("file.R", local = TRUE)

Change it to

source("file.R", local = TRUE)$value

That should fix it
