The ::run command from rmarkdown invokes shiny::runApp internally. You can set the option shiny.host before running the document:

You an also pass arbitrary paramters to runApp, so this should work too:

rmarkdown::run("myfile.Rmd", shiny_args=list(host="0.0.0.0"))

Neither of these will work with the Run Document button; that button starts a new R session in which to render the document. To change the shiny.host option in that session, you'll need to add the option to your .Rprofile.
