r - Shiny Binary Check boxes -

I was thinking that for a glossy check box it is possible to inspect each other in the UI, if I One should be examined, the other should be unchecked, exactly the opposite.

I came to the Function Updates checkbox but the example shown is used for server side, is it possible to check the check box between each other on the UI side?

Thanks,

How is this commonly used for radio buttons Is ? Watch RadioButtons Is there any reason that will not work here?
