Fix port in shinny app

[Harshit Bhargava]

I want to fix my port.I have used options(shiny.port=portno) in ui.R but first time when i run the app it showing different port no.

[Joe Cheng]

Yeah, by the time ui.R runs, it's too late. Why do you need the port fixed?

Hi Joe, We are usng the shinny url in a part of web application.so there we need to pass the url. so we want the port to be fixed so that the url could be easily called rather than changing port numbers.

Ideally you should be running Shiny Server. But if you're going to run Shiny standalone, then just provide the port number explicitly when calling runApp.

Hi Joe, Is there any other way becuase my manager want the same to be run through the rtsudio runApp button.rather than explicitly calling the runApp explicitly through some command.

[Joe Cheng]

Oh, fair enough. There's another solution that is possible which is to use the app.R single file style of Shiny app, and include the option on your shinyApp object. However this requires a newer version of Shiny than is currently on CRAN.

library(shiny)

ui <- fluidPage(...)

server <- function(input, output, session) {
...
}

shinyApp(ui, server, options = list(
port = 8100
))

Hi Joe,Thanks for the quick response.

I have installed latest shiny version using the following command 

if (!require("devtools"))

install.packages("devtools")

devtools::install_github("rstudio/shiny")

then i have clubbed my ui.r and server.r into a single app.r file with the shinyApp(ui = ui, server = server, options = list(

  port = 4110

))

at last of my code

but still i am redirecting to other port than 4110

i.e http://127.0.0.1:7892/

what could be the issue.

I am running shinnyapp through rstudio version -0.99.902
