What is cairo?

Cairo finally catches R's graphics engine, all the way to GE API 16.

Cairo is the R device that renders plots through the cairo library, and until 1.7-0 it lagged R's own graphics engine by several API generations. That release closes the gap to GE API 16 (R 4.5.0), adding fill patterns, masks and groups. The releases before it were maintenance: a segfault shim for grid, a bashism removal in configure, and Windows font and build fixes.

What is quantities?

The glue package that makes R carry units and uncertainty through the same calculation.

quantities combines the units and errors packages into one class so values keep both their measurement units and their uncertainty through arithmetic, subsetting and data frame operations. Recent releases have been narrow: fixes to the covariance and correlation implementations, and performance work on the data.frame methods. Most of the release traffic is coordination with its two parent packages.

Cairo finally catches R's graphics engine, all the way to GE API 16.

◆ Current state

Cairo is the R device that renders plots through the cairo library, and until 1.7-0 it lagged R's own graphics engine by several API generations. That release closes the gap to GE API 16 (R 4.5.0), adding fill patterns, masks and groups. The releases before it were maintenance: a segfault shim for grid, a bashism removal in configure, and Windows font and build fixes.

◆ Where it's heading

The arc is catch-up, executed one API generation at a time. Glyph rendering arrived in 1.6-3, GE 15 stubs in 1.6-5 existed only to stop grid from segfaulting, and 1.7-0 delivers the real GE 13/14/16 feature set rather than placeholders. Alongside that, dropping the CAIROGD_VER C API and the mkdist step means the package now builds with plain R CMD build, which reads as deliberate reduction of maintenance overhead.

◆ Prediction

Expect the next releases to be corrective rather than additive: the entries show every API adoption here has been followed by a fix release, and patterns, masks and groups are a much larger surface than glyphs were.

The glue package that makes R carry units and uncertainty through the same calculation.

◆ Current state

quantities combines the units and errors packages into one class so values keep both their measurement units and their uncertainty through arithmetic, subsetting and data frame operations. Recent releases have been narrow: fixes to the covariance and correlation implementations, and performance work on the data.frame methods. Most of the release traffic is coordination with its two parent packages.

◆ Where it's heading

The design settled with 0.2.0, which made uncertainty unit-aware and added correlation and covariance support for quantities objects. Since then the package behaves like the integration layer it is — releasing when units, errors, dplyr or ggplot2 shift underneath it rather than on its own schedule. Several releases consist only of test repairs against upstream changes.

◆ Prediction

Expect the next release to follow a units or errors change rather than introduce new behaviour of its own.

Frequently asked questions

What is the difference between cairo and quantities?

They serve adjacent needs but don't currently overlap on shipped themes. cairo and quantities are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is cairo better than quantities?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. cairo and quantities are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
