Shiny app in sas studio

ManuelaVila — Mon, 29 Jun 2020 14:25:37 GMT

Hi im transferring an R code to sas using the "submit / R;" of IML. My code has a shiny app and when i try to run it, it doesnt give me an error but it never stops running:

Heres a simple example of what im trying to do

proc iml;
print "-------------  R Results  --------------------";
submit / R;




  library(dplyr)
  library(lubridate)
  library(shiny)
  ui <- fluidPage(
    "The population of France in 1972 was",
    textOutput("answer")
)

# Define the server function
server <- function(input, output) {
    output$answer <- renderText({
        
        "50,763,920"  })
}
endsubmit;

thanks!

It doesn't make much sense to try to call Shiny from SAS. Shiny is a tool for making a WEBPAGE. Did you want SAS to open a URL in a browser to look at the webpage that Shiny is building?

Instead look at the actual R functions that your Shiny app is calling and just call those in the R code you submit via PROC IML.

What types of output does your R function generate? How do you want to return that to SAS?

i need the shiny app because in there i select the variables i need based on a reactive graph that changes depending of what i choose.

Shiny apps require a running R server to host them, which is usually the R Installation or they're hosted elsewhere. They do not generate a self hosting HTML page so I'm not sure that this approach would work at all.
