What is deeptime?

A geologic-time plotting layer that outgrew time axes and became a geology rendering toolkit.

deeptime extends ggplot2 with geological time scales, radial deep-time coordinates and phylogeny-aware geoms, and since 2.0.0 it also renders standardized FGDC/USGS geologic patterns as ggplot2 fills. The current 2.4.0 release adds geom_text_clade() for labeling clades on radial phylogenies and repairs long-standing coord_trans_xy() and scale-placement edge cases.

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.

0.0

A geologic-time plotting layer that outgrew time axes and became a geology rendering toolkit.

◆ Current state

deeptime extends ggplot2 with geological time scales, radial deep-time coordinates and phylogeny-aware geoms, and since 2.0.0 it also renders standardized FGDC/USGS geologic patterns as ggplot2 fills. The current 2.4.0 release adds geom_text_clade() for labeling clades on radial phylogenies and repairs long-standing coord_trans_xy() and scale-placement edge cases.

◆ Where it's heading

The package is converging on two jobs: being the canonical R renderer for stratigraphic drawing conventions, and keeping pace with ggplot2's own churn. A sustained deprecation program — gggeo_scale(), coord_geo_polar(), getScaleData(), now disparity_through_time() — is trimming the surface down to coord_geo(), coord_geo_radial() and the pattern functions. Roughly half of each recent release is ggplot2 4.0 compatibility work.

◆ Prediction

Expect disparity_through_time() and coord_geo_polar() to be removed outright in the next major version, and further geoms aimed at annotating radial phylogenies.

0.0

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 deeptime and quantities?

They serve adjacent needs but don't currently overlap on shipped themes. deeptime 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 deeptime better than quantities?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. deeptime and quantities are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). For your specific use case, the alternatives sections above list other Analytics products to evaluate alongside.
