Exercise

"Hello, World" app output (UI/Server)

To finish up your "Hello, world" app, you'll have to actually display the text that's input.

Recall this is how you construct an output from an input:

# Render output y using input x
output$y <- renderText({
  input$x
})

shiny has been pre-loaded for you.

By the end of this exercise, your app should look like this: Web app that asks a user to enter a name and then displays "Hello name"

If you get an error message resembling Parsing error in script.R:4:3: unexpected symbol, it is very likely that you have forgotten to use a comma to separate the arguments to one of the functions.
