R Question

Is there a way to create R shiny App that receives R commands from user interface?

I want to create a shiny application that has an input for writing some R function or Command, reads it through the ui.R then passes it to the server.R that executes that R command to display the results.

I spent hours searching about some example but couldn't find anything, I already know how to create Shiny apps using ui and server and pass the input values to server and work with them, but I have no idea if it's possible to create a shiny app like R where you can write the commands and return the results, any example or help would be appreciated.

Letting users run code in your app is bad practice, since it comes with great security risks. However, for development you might want to check this function from the shinyjs package by Dean Attali.

Example from the link:


    ui = fluidPage(
      useShinyjs(),  # Set up shinyjs
      runcodeUI(code = "shinyjs::alert('Hello!')")
    server = function(input, output) {
