This variable name is used in the application development and not seen by the user. The character string assigned to the inputId argument will be the variable name used to access the value(s) selected or provided by the user. All widget functions, at minimum, include an inputId and label argument. In the subsequent development we’ll use slider bars, dropdown menus, and check boxes. Shiny package widgets are used to collect user provided inputs (visit the Shiny Widget Gallery to get a sense of the different kinds of input dialogues). There are two ways to do this: 1) use the RStudio button (See Figure 8.2) or 2) type the function runApp() in the RStudio console.

Copy the code in “app.R version 1” into app.R.

In the “ShinyPractice” directory, create a blank R script called app.R.

Create a new directory called “ShinyPractice”.

Follow the subsequent steps to create and run this Shiny app (note these steps are already done for you in the “ShinyPractice” directory in “shiny_chapter_code.zip”, but you might want to do it yourself): The script file that defines this basic application is called app.R and is provided in the code block below called “version 1”.

We begin by defining a very basic Shiny application script upon which we can build the desired functionality. Given the namesDF data, our goal over the next few sections is to develop a Shiny application that allows users to explore age distributions for males and females. $ Last : chr "Poole" "Dowd" "Wilkins" "Murray". $ First: chr "Sarah" "Boris" "Jessica" "Diane".
