Description

These are a S3 generics with built-in methods for names, calls, formuals, and strings. The distinction between a name and a call is particularly important when coercing from a string. Coercing to a call will parse the string, coercing to a name will create a (potentially) non-syntactic name.

Usage

as_name(x)

as_call(x)

Arguments

x	An object to coerce

Examples

as_name("x + y")
as_call("x + y")

as_call(~ f)
as_name(~ f())
