You are correct that indefinite means an antiderivative. A definite integral has both limits specified. Technically correct terms are: proper and improper definite integrals (although improper integrals are not synonymous with, but include integrals with an infinite range). Your suggestion is perfectly fine.

In 'Writing R Extensions' section 6.9 there is the paragraph
There are interfaces (defined in header R_ext/Applic.h) for definite and for indefinite integrals. ‘Indefinite’ means that at least one of the integration boundaries is not finite.
An indefinite integral usually means an antiderivative, not an integral over an infinite spread. Should that first sentence end with 'for integrals over finite and infinite ranges' and the second sentence omitted?
