Optional Slider Input Widget — optionalSliderInput • teal.widgets

Hidden input widgets are useful to have the input[[inputId]] variable on available in the server function but no corresponding visual clutter from input widgets that provide only a single choice.

Usage

optionalSliderInput(inputId, label, min, max, value, label_help = NULL, ...)

Arguments

inputId: The input slot that will be used to access the value.
label: Display label for the control, or NULL for no label.
min, max: The minimum and maximum values (inclusive) that can be selected.
value: The initial value of the slider, either a number, a date (class Date), or a date-time (class POSIXt). A length one vector will create a regular slider; a length two vector will create a double-ended range slider. Must lie between min and max.
label_help: (shiny.tag) optional
object of class shiny.tag, e.g. an object returned by shiny::helpText()
...: optional arguments to sliderInput

Value

(shiny.tag) HTML tag with sliderInput widget.

Details

if min or max are NA then the slider widget will be hidden
