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 epikit?

epikit narrows to field-epidemiology helpers, handing proportions to a sibling package

epikit is a set of small helpers for applied epidemiology in R — age categorisation, date reconstruction from partial records, and related field-data chores, developed in the R4Epis orbit. Version 0.2.0 moved the proportion functions out to epitabulate, improved how find_date_cause(), find_start_date() and find_end_date() handle dates falling outside the period, and added a floor argument to age_categories() so the lowest band reads as under one rather than zero to zero.

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.

epikit narrows to field-epidemiology helpers, handing proportions to a sibling package

◆ Current state

epikit is a set of small helpers for applied epidemiology in R — age categorisation, date reconstruction from partial records, and related field-data chores, developed in the R4Epis orbit. Version 0.2.0 moved the proportion functions out to epitabulate, improved how find_date_cause(), find_start_date() and find_end_date() handle dates falling outside the period, and added a floor argument to age_categories() so the lowest band reads as under one rather than zero to zero.

◆ Where it's heading

The package is being scoped down rather than built out. The 0.1.3 restructuring and the 0.2.0 handover of proportions to epitabulate are the same move made twice: push functionality into the package where it belongs and keep epikit to the toolkit that field epidemiologists reach for directly. The rest of the history is dependency compatibility work against dplyr and tibble.

◆ Prediction

With proportions gone and dependencies trimmed, the remaining functions cluster tightly around dates and age bands, so further refinement of the date-reconstruction helpers is more likely than new capability areas.

Frequently asked questions

What is the difference between deeptime and epikit?

They serve adjacent needs but don't currently overlap on shipped themes. deeptime and epikit 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 epikit?

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