profvis example for shiny app

[Wei Zou]

Hi, I saw Garrett did a demo to use profvis within a shiny app. it is very impressive. But when I tried it in several parts of my server.R file, none of them worked. Can someone post a few examples to use profvis in shiny app?

thanks

I think you need to wrap the entire app in profvis. Probably best to use it on self contained pieces of code anyways.

Call profvis({ shiny::runApp() }) or something like that to use profvis with Shiny.

Hi Joe,

My Shiny app is writen in server.R and ui.R with many modules. I try to warp shiny::runApp with profvis, but one error happened. I am confused with this. 

# Run dashboard app on port 8888

require(shiny)

library(profvis)

profvis({

  shiny::runApp(

    appDir = dirname(sys.frame(1)$ofile),

    port = 8888,

    launch.browser = FALSE,

    quiet = TRUE)

})

profvis: code exited with error:

not that many frames on the stack
