shiny.tailwind (version 0.2.2)

twSliderInput: Wrapper around shiny::sliderInput() but allowing for more classes

Description

Note that the colors for the slider bar can be customized by overriding the irs class. c.f. 05-apply-directive example app

Usage

twSliderInput(
  inputId,
  label,
  min,
  max,
  value,
  step = NULL,
  round = FALSE,
  ticks = TRUE,
  animate = FALSE,
  width = NULL,
  sep = ",",
  pre = NULL,
  post = NULL,
  timeFormat = NULL,
  timezone = NULL,
  dragRange = TRUE,
  container_class = NULL,
  label_class = NULL,
  input_class = NULL,
  label_after_input = FALSE
)

Value

a list with a shiny.tag class

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.

step

Specifies the interval between each selectable value on the slider. Either NULL, the default, which uses a heuristic to determine the step size or a single number. If the values are dates, step is in days; if the values are date-times, step is in seconds.

round

TRUE to round all values to the nearest integer; FALSE if no rounding is desired; or an integer to round to that number of digits (for example, 1 will round to the nearest 10, and -2 will round to the nearest .01). Any rounding will be applied after snapping to the nearest step.

ticks

FALSE to hide tick marks, TRUE to show them according to some simple heuristics.

animate

TRUE to show simple animation controls with default settings; FALSE not to; or a custom settings list, such as those created using animationOptions().

width

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

sep

Separator between thousands places in numbers.

pre

A prefix string to put in front of the value.

post

A suffix string to put after the value.

timeFormat

Only used if the values are Date or POSIXt objects. A time format string, to be passed to the Javascript strftime library. See https://github.com/samsonjs/strftime for more details. The allowed format specifications are very similar, but not identical, to those for R's base::strftime() function. For Dates, the default is "%F" (like "2015-07-01"), and for POSIXt, the default is "%F %T" (like "2015-07-01 15:32:10").

timezone

Only used if the values are POSIXt objects. A string specifying the time zone offset for the displayed times, in the format "+HHMM" or "-HHMM". If NULL (the default), times will be displayed in the browser's time zone. The value "+0000" will result in UTC time.

dragRange

This option is used only if it is a range slider (with two values). If TRUE (the default), the range can be dragged. In other words, the min and max can be dragged together. If FALSE, the range cannot be dragged.

container_class

additional classes to be applied to the container

label_class

additional classes to be applied to the label

input_class

additional classes to be applied to the input element

label_after_input

TRUE/FALSE if the label should be put after the input box. Default is FALSE. Useful for special cases (floating labels), c.f. 05-apply-directive example app.

Examples

shiny::sliderInput("values", "A Range", min = 0, max = 100, value = 75)
twSliderInput("values", "A Range",
  min = 0, max = 100, value = 75,
  container_class = "CONTAINER", label_class = "LABEL",
  input_class = "INPUT"
)
