showPageSpinner/hidePageSpinner don't work

[JohnHendrickx]

I'm trying to run the "full-page spinner" example from the readme on this site but showPageSpinner and hidePageSpinner functions aren't recognized. The app runs but if I click "go" I get the following error and the app crashes:

Listening on http://127.0.0.1:4874
Warning: Error in showPageSpinner: could not find function "showPageSpinner"

It's a new feature, not yet available on CRAN version. You need to install the dev version from github.

Hi @daattali - any idea when this will be added to the CRAN version?

[daattali]

I want to give it some time because there's a lot of new features in this version and they're not simple, so there's a lot of potential room for bugs. So I want to allow another month for beta testing by users
