Developing Data Products Quiz Answers

Week 1 Quiz Answers

Quiz 1: Quiz 1

Q1. Which of the following are absolutely necessary for creating a functioning shiny app? (Check all that apply)

  • A server.R file containing a call to shinyServer()
  • A ui.R file containing a call to shinyUI()
  • A shiny.R file containing calls to shinyServer() and shinyUI()
  • A ui.R file that contains information about the CSS and styling of the App
  • A server.R file that sets configuration options for hosting the App

Q2. What is incorrect about the following syntax in ui.R?

library(shiny)shinyUI(pageWithSidebar(headerPanel("Data science FTW!"),sidebarPanel(h2('Big text')h3('Sidebar')),mainPanel(h3('Main Panel text'))
  • The h2 command does not take text arguments
  • Missing comma after the h3 command
  • Missing a comma in the sidebar panel
  • The h3 command should be an h2 command

Q3. Consider the following in ui.R


    function(input, output) {    
       output$myHist <- renderPlot({      
          hist(galton$child, xlab='child height', col='lightblue',main='Histogram')      
          mu <- input$mu      
          lines(c(mu, mu), c(0, 200),col="red",lwd=5)      
          mse <- mean((galton$child - mu)^2)      
          text(63, 150, paste("mu = ", mu))      
          text(63, 140, paste("MSE = ", round(mse, 2)))      
          })      }

Why isn’t it doing what we want? (Check all that apply.)

The phrase “Guess at the mu value” should say “mean” instead of “mu”

It should be

mu <- input$mean

in server.R

  • The server.R output name isn’t the same as the plotOutput command used in ui.R.
  • The limits of the slider are set incorrectly and giving an error.

Q4. What are the main differences between creating a Shiny Gadget and creating a regular Shiny App? (Check all that apply)

  • Shiny Gadgets are designed to be used by R users in the middle of a data analysis.
  • Shiny Gadgets are specially designed for use on mobile phones and tablet computers.
  • Shiny Gadgets are designed to have small user interfaces that fit on one page.
  • Shiny Gadgets can be run on a user’s personal computer, unlike a regular Shiny App which needs to be hosted online.
  • Shiny Gadgets are smaller programs and therefore run faster than Shiny Apps.

Q5. Consider the following R script:


pickXY <- function() {
  ui <- miniPage(
    gadgetTitleBar("Select Points by Dragging your Mouse"),
      plotOutput("plot", height = "100%", brush = "brush")

  server <- function(input, output, session) {
      output$plot <- renderPlot({
        plot(data_frame$X, data_frame$Y, main = "Plot of Y versus X",
           xlab = "X", ylab = "Y")
      observeEvent(input$done, {
        stopApp(brushedPoints(data_frame, input$brush,
                          xvar = "X", yvar = "Y"))

  runGadget(ui, server)

my_data <- data.frame(X = rnorm(100), Y = rnorm(100))


Why isn’t it doing what we want?

  • The input data is defined in such a way that it is not compatible with pickXY()
  • The wrong column names are passed to brushedPoints()
  • No arguments are defined for pickXY()
  • The call to plot() references the column names of the data frame in the wrong order.
