formatNumericInput: Format Numeric Inputs

In shinyWidgets: Custom Inputs Widgets for Shiny

Format Numeric Inputs

Description

Shiny widgets for as-you-type formatting of currency and numeric values. For a more modifiable version see autonumericInput(). These two functions do the exact same thing but are named differently for more intuitive use (currency for money, formatNumeric for percentage or other).

Usage

currencyInput(
  inputId,
  label,
  value,
  format = "euro",
  width = NULL,
  align = "center"
)

formatNumericInput(
  inputId,
  label,
  value,
  format = "commaDecimalCharDotSeparator",
  width = NULL,
  align = "center"
)

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 (unformatted).
format	A character string specifying the currency format of the input. See "Details" for possible values.
width	The width of the input box, eg. "200px" or "100%".
align	The alignment of the text inside the input box, one of "center", "left", "right". Defaults to "center".

Details

In regards to format, there are currently 41 sets of predefined options that can be used, most of which are variations of one another. The most common are:

• "French"

• "Spanish"

• "NorthAmerican"

• "British"

• "Swiss"

• "Japanese"

• "Chinese"

• "Brazilian"

• "Turkish"

• "euro" (same as "French")

• "dollar" (same as "NorthAmerican")

• "percentageEU2dec"

• "percentageUS2dec"

• "dotDecimalCharCommaSeparator"

• "commaDecimalCharDotSeparator"
