updateDateInput

updateDateInput(session, inputId, label = NULL, value = NULL,
  min = NULL, max = NULL)

Arguments

session	The session object passed to function given to shinyServer.
inputId	The id of the input object.
label	The label to set for the input object.
value	The desired date value. Either a Date object, or a string in yyyy-mm-dd format. Supply NA to clear the date.
min	The minimum allowed date. Either a Date object, or a string in yyyy-mm-dd format.
max	The maximum allowed date. Either a Date object, or a string in yyyy-mm-dd format.

Description

Change the value of a date input on the client

Details

The input updater functions send a message to the client, telling it to change the settings of an input object. The messages are collected and sent after all the observers (including outputs) have finished running.

The syntax of these functions is similar to the functions that created the inputs in the first place. For example, numericInput() and updateNumericInput() take a similar set of arguments.

Any arguments with NULL values will be ignored; they will not result in any changes to the input object on the client.

For radioButtons(), checkboxGroupInput() and selectInput(), the set of choices can be cleared by using choices=character(0). Similarly, for these inputs, the selected item can be cleared by using selected=character(0).

Examples

## Only run examples in interactive R sessions
if (interactive()) {

ui <- fluidPage(
  sliderInput("n", "Day of month", 1, 30, 10),
  dateInput("inDate", "Input date")
)

server <- function(input, output, session) {
  observe({
    date <- as.Date(paste0("2013-04-", input$n))
    updateDateInput(session, "inDate",
      label = paste("Date label", input$n),
      value = date,
      min   = date - 3,
      max   = date + 3
    )
  })
}

shinyApp(ui, server)
}
