Arguments

pr

Either a tableau_extension style Plumber router object, or, the filename of a plumber.R that implements a Tableau extension.

...

Zero or more unnamed arguments to be passed to the script.

Additional options that should be passed to jsonlite::toJSON() when the ... arguments are serialized; for example, pretty = TRUE or digits = 8.
