@divibisan basically said it all in his comment. When you want to run a R script, you can use the command source as in

source("path/to/my/script.R")

All relative paths will be resolved based on your working directory (getwd()). If you have a shiny app and a script file (script.R) in the same directory, you can use

## file: app.R
shinyApp(
  fluidPage(
    actionButton("buttonId", "run script")
  ),
  function(input, output, session) {
    observeEvent(input$buttonId, {
      message("running script.R")
      source("script.R")
    })
  }
)

Then you run the app with

shiny::runApp("app.R")

or you just use the "run app" button in RStudio.

I dont't really get what you mean with "display the script name". You just include it in the ui?
