input_slider {ggvis}

Create an interactive slider.

Description

Create an interactive slider.

Usage

input_slider(
  min,
  max,
  value = (min + max)/2,
  step = NULL,
  round = FALSE,
  format = NULL,
  locale = "us",
  ticks = TRUE,
  animate = FALSE,
  sep = ",",
  pre = NULL,
  post = NULL,
  label = "",
  id = rand_id("slider_"),
  map = identity
)

Arguments

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.

format

A string specifying how to format the value.

locale

A string specifying the locale to use for formatting.

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().

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.

label

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

id

A unique identifier for this input. Usually generated automatically.

map

A function with single argument x, the value of the control on the client. Returns a modified value.

Examples

input_slider(0, 100)
input_slider(0, 100, label = "binwidth")
input_slider(0, 100, value = 50)

# Supply two values to value to make a double-ended sliders
input_slider(0, 100, c(25, 75))

# You can use map to transform the outputs
input_slider(-5, 5, label = "Log scale", map = function(x) 10 ^ x)
