rolap vs rrum
A side-by-side editorial comparison of rolap and rrum — release velocity, themes, recent moves, and the top alternatives to consider.
Shared themes:r-package
rolap vs rrum: at a glance
What is rolap?
A star-schema modelling package grew a query language, a deployment path, and then a map layer.
rolap builds dimensional models — star databases and constellations — from flat tables inside R. Over 2023 it acquired a multidimensional query interface, the ability to deploy models into relational databases, incremental refresh, and geographic layers exportable as GeoPackage. Since early 2024 it has been quiet, with the only 2025 release removing a test that clashed with another package.
What is rrum?
Six years past its API cleanup, rrum ships only what the compiler demands.
rrum estimates the reduced Reparameterized Unified Model via a Gibbs sampler in Rcpp/Armadillo, with simulation delegated to its sibling package simcdm. The user-facing API has been settled since 2019, when the entry point was renamed and simulation was moved out. Releases since then have been build and CRAN compliance work.

rolap
0.0ANALYTICS
A star-schema modelling package grew a query language, a deployment path, and then a map layer.
◆ Current state
rolap builds dimensional models — star databases and constellations — from flat tables inside R. Over 2023 it acquired a multidimensional query interface, the ability to deploy models into relational databases, incremental refresh, and geographic layers exportable as GeoPackage. Since early 2024 it has been quiet, with the only 2025 release removing a test that clashed with another package.
◆ Where it's heading
The 2023 releases trace a deliberate progression from modelling to operating: first a common data model and flat table class, then role-playing dimensions, then incremental refresh, then querying and deployment, then geography, then slowly changing dimensions. That is essentially the feature checklist of a data warehouse, assembled in about six months and documented with a vignette at each step. The pace since has dropped to almost nothing, which reads as a project that reached its intended scope rather than one that stalled.
◆ Prediction
Given eighteen months in which the only release was a test removal, the next release is more likely to be maintenance than another warehouse feature — though the entries give no clear signal either way.
rrum
0.0ANALYTICS
Six years past its API cleanup, rrum ships only what the compiler demands.
◆ Current state
rrum estimates the reduced Reparameterized Unified Model via a Gibbs sampler in Rcpp/Armadillo, with simulation delegated to its sibling package simcdm. The user-facing API has been settled since 2019, when the entry point was renamed and simulation was moved out. Releases since then have been build and CRAN compliance work.
◆ Where it's heading
The arc runs from an API-breaking consolidation in 2019, through a 2023 release fixing C++ deprecations and adding a pkgdown site, to a 2025 maintenance release that raises dependency floors and swaps a deprecated Armadillo conversion call. Each release is triggered by something outside the package — R-devel, CRAN check notes, an Armadillo deprecation — rather than by modeling work. The 2025 release arrived the same morning as a near-identical one for edina, marking it as a maintainer-wide sweep across the lab's packages.
◆ Prediction
The next release will most likely be another externally forced compatibility fix, since three consecutive releases have been reactions to toolchain deprecations rather than to user requests.
