Set the default values you want to initialize in (~/.Rprofile) under user directory

Sys.setenv(TZ = "UTC")  # for Timezone
options(shiny.port = 9999)

Answer 2

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

options(shiny.host="0.0.0.0")
rmarkdown::run("myfile.Rmd")

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.
