R Shiny renderDataTable options
Shiny has upgraded DataTables from 1.9.x to 1.10.x since shiny 0.10.2, and you can use the options listed at http://datatables.net/reference/option/ if your shiny version is higher than 0.10.2.
If this setting is located in a separate file that is sourced by your application (for example: my_app.R sources my_module.R where the datatable is created/defined), then you may need to source the separate file manually (or remove the previous sourced versions from the workspace) to get changes in this setting to show up.
For some reason, even if my_app.R sources my_module.R on run time this setting (and other options like it) are not always picked up.
Manual sourcing of the file has not been necessary for me when the datatable is created in my_app.R, ui.R or server.R.
