Render a value of a class this package does not know

The extension point for a calling package with its own way of describing a value, such as a distribution object. Write a method returning either a spec from julia_spec() or a plain R value, and it renders wherever the value appears.

Usage

as_julia_value(x, ...)

Arguments

x

The value to render.

...

Passed to methods.

Value

A spec or an R value that renders on its own.

Examples

# A package with a value class of its own renders it like this:
as_julia_value.my_interval <- function(x, ...) {
  julia_spec("Interval", x$lower, x$upper)
}
