radioGroupButtons {shinyWidgets}

Buttons Group Radio Input Control

Description

Create buttons grouped that act like radio buttons.

Usage

radioGroupButtons(
  inputId,
  label = NULL,
  choices = NULL,
  selected = NULL,
  status = "default",
  size = "normal",
  direction = "horizontal",
  justified = FALSE,
  individual = FALSE,
  checkIcon = list(),
  width = NULL,
  choiceNames = NULL,
  choiceValues = NULL,
  disabled = FALSE
)

Arguments

inputId

The input slot that will be used to access the value.

label

Display label for the control, or NULL for no label.

choices

List of values to select from (if elements of the list are named then that name rather than the value is displayed to the user). If this argument is provided, then choiceNames and choiceValues must not be provided, and vice-versa. The values should be strings; other types (such as logicals and numbers) will be coerced to strings.

selected

The initially selected value. If not specified, then it defaults to the first item in choices. To start with no items selected, use character(0).

status

Add a class to the buttons, you can use Bootstrap status like 'info', 'primary', 'danger', 'warning' or 'success'. Or use an arbitrary strings to add a custom class, e.g. : with status = "custom-class", buttons will have class btn-custom-class.

size

Size of the buttons ('xs', 'sm', 'normal', 'lg')

direction

Horizontal or vertical

justified

If TRUE, fill the width of the parent div

individual

If TRUE, buttons are separated.

checkIcon

A list, if no empty must contain at least one element named 'yes' corresponding to an icon to display if the button is checked.

width

The width of the input, e.g. '400px', or '100%'; see validateCssUnit().

choiceNames, choiceValues

List of names and values, respectively, that are displayed to the user in the app and correspond to the each choice (for this reason, choiceNames and choiceValues must have the same length). If either of these arguments is provided, then the other must be provided and choices must not be provided. The advantage of using both of these over a named list for choices is that choiceNames allows any type of UI object to be passed through (tag objects, icons, HTML code, ...), instead of just simple text. See Examples.

disabled

Initialize buttons in a disabled state (users won't be able to select a value).

Value

A buttons group control that can be added to a UI definition.

      yes = icon("square-check"),
      no = icon("square")
    )
  ),

)

  output$value1 <- renderPrint({ input$somevalue1 })
  output$value2 <- renderPrint({ input$somevalue2 })
  output$value3 <- renderPrint({ input$somevalue3 })

}
