  function given to \code{shinyServer}.}

  \item{inputId}{The id of the input object.}

  \item{label}{The label to set for the input object.}

  \item{value}{The desired date value. Either a Date
  object, or a string in \code{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,
  \code{\link{numericInput}()} and
  \code{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.

      value = paste("2013-04-", x, sep=""),
      min   = paste("2013-04-", x-1, sep=""),
