updateDateRangeInput

From shiny v0.12.2 by Winston Chang

Change the start and end values of a date range input on the client

Usage

updateDateRangeInput(session, inputId, label = NULL, start = NULL,
  end = 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.
start: The start date. Either a Date object, or a string in yyyy-mm-dd format.
end: The end date. Either a Date object, or a string in yyyy-mm-dd format.
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.

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.

Examples

shinyServer(function(input, output, session) {

  observe({
    # We'll use the input$controller variable multiple times, so save it as x
    # for convenience.
    x <- input$controller

    updateDateRangeInput(session, "inDateRange",
      label = paste("Date range label", x),
      start = paste("2013-01-", x, sep=""))
      end = paste("2013-12-", x, sep=""))
  })
})
