Constructs a slider widget to select a number, date, or date-time from a range.
sliderInput(
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
)animationOptions(
interval = 1000,
loop = FALSE,
playButton = NULL,
pauseButton = NULL
)
The input slot that will be used to access the value.
Display label for the control, or NULL for no label.
The minimum and maximum values (inclusive) that can be selected.
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.
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.
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.
FALSE to hide tick marks, TRUE to show them
according to some simple heuristics.
TRUE to show simple animation controls with default
settings; FALSE not to; or a custom settings list, such as those
created using animationOptions().
The width of the input, e.g. '400px', or '100%';
see validateCssUnit().
Separator between thousands places in numbers.
A prefix string to put in front of the value.
A suffix string to put after the value.
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").
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.
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.
The interval, in milliseconds, between each animation step.
TRUE to automatically restart the animation when it
reaches the end.
Specifies the appearance of the play button. Valid values
are a one-element character vector (for a simple text label), an HTML tag
or list of tags (using tag() and friends), or raw HTML (using
HTML()).
Similar to playButton, but for the pause button.
A number, date, or date-time (depending on the class of value), or
in the case of slider range, a vector of two numbers/dates/date-times.
