R: Get or set Shiny options

getShinyOption {shiny} | R Documentation

## Get or set Shiny options

### Description

`getShinyOption` retrieves the value of a Shiny option. `shinyOptions` sets the value of Shiny options; it can also be used to return a list of all currently-set Shiny options.

### Usage

    getShinyOption(name, default = NULL)

    shinyOptions(...)

### Arguments

`name` | Name of an option to get.
`default` | Value to be returned if the option is not currently set.
`...` | Options to set, with the form `name = value`.

### Details

There is a global option set, which is available by default. When a Shiny application is run with `runApp`, that option set is duplicated and the new option set is available for getting or setting values. If options are set from global.R, app.R, ui.R, or server.R, or if they are set from inside the server function, then the options will be scoped to the application. When the application exits, the new option set is discarded and the global option set is restored.

### Examples

    ## Not run:
    shinyOptions(myOption = 10)
    getShinyOption("myOption")

    ## End(Not run)
