  3. Creating Dashboards with shinydashboard

Exercise

Review selectInput and sliderInput

As a quick refresher, using the dashboardSidebar() function along with selectInput() and sliderInput() from the shiny package, you can create select lists and sliders. For example, to create a select list in the sidebar, you can do the following:

sidebar <- dashboardSidebar(
  selectInput(inputId = "numbers",
              label = "Numbers",
              choices = 1:3)
  )

For this chapter, we are working with the dplyr starwars dataset, a data set pulled from the Star Wars API containing information about characters from Star Wars. We are interested in creating a subset of the data set of characters between specified height parameters. For this exercise, create a slider to indicate the maximum height you'd like in your subset.

Instructions

100 XP
  • Create a slider in the sidebar with the following parameters:
  • inputId: "height", label: "Height", min: 66, max: 264, value: 264.
  • Rerun the shiny app with these updates.
