numberInput: Create a numeric input

In jdtrat/shinysurveys: Create and Deploy Surveys in 'Shiny'

Create a numeric input

Description

Create an input control for entry of numeric values. This is identical to shiny::numericInput() but is more flexible in not requiring an initial value and in allowing placeholders.

Usage

numberInput(
  inputId,
  label,
  value = NULL,
  min = NA,
  max = NA,
  step = NA,
  placeholder = NULL,
  width = NULL
)

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. NULL by default.
min	Minimum allowed value
max	Maximum allowed value
step	Interval to use when stepping between min and max
placeholder	A character string giving the user a hint as to what can be entered into the control. Internet Explorer 8 and 9 do not support this option.
width	The width of the input, e.g. '400px', or '100%'; see validateCssUnit().

Value

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

Server value

A numeric vector of length 1.

Examples

if (interactive()) {
library(shiny)
library(shinysurveys)

ui <- fluidPage(
  numberInput("obs", "Observations:", placeholder = "How many do you see?", min = 1, max = 100),
  verbatimTextOutput("value")
)
server <- function(input, output) {
  output$value <- renderText({ input$obs })
}
shinyApp(ui, server)
}
