Create a numeric input control — numericInput

v1.11.1|Source: R/input-numeric.R

Description

Create an input control for entry of numeric values

numericInput(
  inputId,
  label,
  value,
  min = NA,
  max = NA,
  step = NA,
  width = NULL,
  ...,
  updateOn = c("change", "blur")
)

Arguments

inputId

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

label

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

value

Initial value.

min

Minimum allowed value

max

Maximum allowed value

step

Interval to use when stepping between min and max

width

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

...

Ignored, included to require named arguments and for future feature expansion.

updateOn

A character vector specifying when the input should be updated. Options are "change" (default) and "blur". Use "change" to update the input immediately whenever the value changes. Use "blur"to delay the input update until the input loses focus (the user moves away from the input), or when Enter is pressed (or Cmd/Ctrl + Enter for textAreaInput()).

Value

A numeric input control that can be added to a UI definition.

Server value

A numeric vector of length 1.
