What is clock?

clock is turning calendar conventions lubridate hard-coded into parameterized types.

clock provides typed date-time handling for R on top of the C++20 date library, with explicit calendar and time-point types instead of implicit coercion. The visible history splits between genuine arithmetic additions and a long tail of compiler and CRAN-policy repairs. Recent releases are mostly the latter, with 0.7.3 raising the tzdb and R floors.

What is ellipsis?

ellipsis' checks live in rlang now; the package is a compatibility shim.

ellipsis provides check_dots_used(), check_dots_unnamed() and check_dots_empty() for catching arguments silently swallowed by dots. Its functional development finished in 2019 across the 0.2.0 and 0.3.0 releases. The two releases since deal only with rlang and CRAN, and 0.3.3 makes the rlang dependency unconditional.

clock is turning calendar conventions lubridate hard-coded into parameterized types.

◆ Current state

clock provides typed date-time handling for R on top of the C++20 date library, with explicit calendar and time-point types instead of implicit coercion. The visible history splits between genuine arithmetic additions and a long tail of compiler and CRAN-policy repairs. Recent releases are mostly the latter, with 0.7.3 raising the tzdb and R floors.

◆ Where it's heading

The feature arc moves toward making conventions explicit and parameterized rather than fixed: counting units between dates in 0.6.0, duration modulus and integer division alongside it, then a week-start-parameterized calendar in 0.7.0 that subsumes both ISO and CDC epidemiological weeks. Since 0.7.0 the package has added almost no surface, spending releases on C++ toolchain compliance instead. The 0.7.3 parsing change, following upstream to character-width rather than digit-count parsing, is the one recent break users must handle.

◆ Prediction

The last three releases are maintenance-shaped, so the next most likely tracks another tzdb or compiler requirement rather than adding calendars.

0.0

ellipsis' checks live in rlang now; the package is a compatibility shim.

◆ Current state

ellipsis provides check_dots_used(), check_dots_unnamed() and check_dots_empty() for catching arguments silently swallowed by dots. Its functional development finished in 2019 across the 0.2.0 and 0.3.0 releases. The two releases since deal only with rlang and CRAN, and 0.3.3 makes the rlang dependency unconditional.

◆ Where it's heading

The package built its full surface quickly, hardened it once by switching the check functions from warnings to errors, then saw the ideas move upstream. These checks are part of rlang's own API now, which leaves ellipsis as a compatibility layer for packages still importing it directly. The 0.3.3 change to depend on rlang unconditionally states that relationship plainly.

◆ Prediction

With the functionality living in rlang, the next release is most likely another CRAN-driven fix; there is no sign of new checks being added here.
