\description{
|
|
Change the start and end values of a date range 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.
