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