lang_modify: Manipulate or access a call

Description

These functions are soft-deprecated, please use call_modify(), call_standardise(), or call_fn() instead.

Usage

lang_modify(.lang, ..., .standardise = FALSE)
lang_standardise(lang)
lang_fn(lang)
lang_name(lang)
lang_args(lang)
lang_args_names(lang)

Arguments

...

Named or unnamed expressions (constants, names or calls) used to modify the call. Use NULL to remove arguments. These dots support tidy dots features.

.standardise

If TRUE, the call is standardised beforehand to match existing unnamed arguments to their argument names. This prevents new named arguments from accidentally replacing original unnamed arguments.

lang, .lang

The call or .call argument of the renamed functions.
