Use @inheritParams rlang::args_error_context
in your package to
document arg
and call
arguments (or equivalently their prefixed
versions error_arg
and error_call
).
arg
parameters should be formatted as argument (e.g. using cli's.arg
specifier) and included in error messages. See alsocaller_arg()
.call
parameters should be included in error conditions in a field namedcall
. An easy way to do this is by passing acall
argument toabort()
. See alsolocal_error_call()
.
