What is fossilsim?

A fossil-record simulator that quietly grew a trait-evolution engine.

FossilSim is a mature R package for simulating fossil records on phylogenetic trees, and its release cadence reflects that: long gaps punctuated by a single capability addition. The last four releases span three years, with the most recent being a compatibility sync to its companion Shiny front-end rather than new functionality. The core simulation surface has been stable since 2022.

What is omock?

A mock-data generator for OMOP studies that keeps widening what it can fake.

omock builds synthetic OMOP Common Data Model tables so packages in the darwin-eu and OHDSI ecosystem can be tested without touching patient data. The 0.7.0 release adds concept set subsetting with its own vignette, unit and value support in mockMeasurement, observation date validation and cohort attrition initialization, while deprecating mockConcepts. Releases arrive as PR digests rather than written notes.

A fossil-record simulator that quietly grew a trait-evolution engine.

◆ Current state

FossilSim is a mature R package for simulating fossil records on phylogenetic trees, and its release cadence reflects that: long gaps punctuated by a single capability addition. The last four releases span three years, with the most recent being a compatibility sync to its companion Shiny front-end rather than new functionality. The core simulation surface has been stable since 2022.

◆ Where it's heading

The arc runs from sampling mechanics toward simulating what the organisms actually were. Version 2.2.0 taught the package to handle occurrence data for occurrence birth-death models; 2.3.0 then added trait simulation under Mk, BM and OU, which is a different kind of output than fossil ages. Since then the work has been maintenance and keeping the FossilSimShiny GUI in step, suggesting the authors consider the current model set feature-complete.

◆ Prediction

The pairing of the 2.3.3 release with a FossilSimShiny version bump points to the GUI, not the library, as where the next visible work lands. The entries do not show enough activity to predict a specific new model family.

0.0

A mock-data generator for OMOP studies that keeps widening what it can fake.

◆ Current state

omock builds synthetic OMOP Common Data Model tables so packages in the darwin-eu and OHDSI ecosystem can be tested without touching patient data. The 0.7.0 release adds concept set subsetting with its own vignette, unit and value support in mockMeasurement, observation date validation and cohort attrition initialization, while deprecating mockConcepts. Releases arrive as PR digests rather than written notes.

◆ Where it's heading

The package has been moving from generating tables to shipping and managing reference datasets — mockDatasets arrived in 0.4.0, mockCdmFromDataset gained a source argument in 0.5.0, and 0.6.1 added download retry handling plus an internal GiBleed dataset after the hosted files moved. The recent work is filling in CDM fidelity: type concepts, measurement units, attrition, and guards for degenerate cases like an empty person table.

◆ Prediction

Expect coverage to keep extending table by table toward the parts of the CDM that omock still cannot mock, with mockConcepts removed outright once the concept set subsetting path settles.
