\arguments{
|
|
\item{expr}{An expression that returns a data frame or a matrix.}
|
|
|
|
\item{options}{A list of initialization options to be passed to DataTables,
|
|
or a function to return such a list.}
|
|
|
|
\item{searchDelay}{The delay for searching, in milliseconds (to avoid too
|
|
frequent search requests).}
|
|
|
|
\item{callback}{A JavaScript function to be applied to the DataTable object.
|
|
This is useful for DataTables plug-ins, which often require the DataTable
|
|
instance to be available (\url{http://datatables.net/extensions/}).}
|
|
|
|
\item{escape}{Whether to escape HTML entities in the table: \code{TRUE} means
|
|
to escape the whole table, and \code{FALSE} means not to escape it.
|
|
Alternatively, you can specify numeric column indices or column names to
|
|
indicate which columns to escape, e.g. \code{1:5} (the first 5 columns),
|
|
\code{c(1, 3, 4)}, or \code{c(-1, -3)} (all columns except the first and
|
|
third), or \code{c('Species', 'Sepal.Length')}.}
|
|
|
|
\item{env}{The environment in which to evaluate \code{expr}.}
|
|
|
|
\item{quoted}{Is \code{expr} a quoted expression (with \code{quote()})? This
|
|
is useful if you want to save an expression in a variable.}
|
|
|
|
\item{outputArgs}{A list of arguments to be passed through to the implicit
|
|
call to \code{\link{dataTableOutput}} when \code{renderDataTable} is used
|
|
in an interactive R Markdown document.}
|
|

\description{
|
|
Makes a reactive version of the given function that returns a data frame (or
|
|
matrix), which will be rendered with the DataTables library. Paging,
|
|
searching, filtering, and sorting can be done on the R side using Shiny as
|
|
the server infrastructure.
|
|
}
|
|
\details{
|
|
For the \code{options} argument, the character elements that have the class
|
|
\code{"AsIs"} (usually returned from \code{\link[base]{I}()}) will be evaluated in
|
|
JavaScript. This is useful when the type of the option value is not supported
|
|
in JSON, e.g., a JavaScript function, which can be obtained by evaluating a
|
|
character string. Note this only applies to the root-level elements of the
|
|
options list, and the \code{I()} notation does not work for lower-level
|
|
elements in the list.
|
|
}
|
|
\note{
|
|
This function only provides the server-side version of DataTables
|
|
(using R to process the data object on the server side). There is a
|
|
separate package \pkg{DT} (\url{https://github.com/rstudio/DT}) that allows
|
|
you to create both server-side and client-side DataTables, and supports
|
|
additional DataTables features. Consider using \code{DT::renderDataTable()}
|
|
and \code{DT::dataTableOutput()} (see
|
|
\url{http://rstudio.github.io/DT/shiny.html} for more information).
