I just stumbled on shinytableau, and it looks fantastic! One quick question...I seem to be able to embed a Shiny app that is hosted on our internal Shiny server into an internal Tableau dashboard by just embedding the URL for the app in an iFrame on the Tableau dashboard (without even using shinytableau). If that gives me all the functionality I'm needing, what are the advantages of converting to run with shinytableau? Is there a reason I shouldn't be just embedding apps via iFrames? Thanks!
