edina vs rolap
A side-by-side editorial comparison of edina and rolap — release velocity, themes, recent moves, and the top alternatives to consider.

edina vs rolap: at a glance
What is edina?
A finished psychometric estimator kept alive by toolchain upkeep, not new modeling work.
edina is a single-purpose Rcpp/Armadillo implementation of the Exploratory DINA model, feature-complete since its 2020 debut. Its entire visible surface — estimation plus Q-matrix comparison across k values — has not changed in five years. The only 2025 activity is a maintenance release that raises the R, Rcpp and RcppArmadillo floors so the package still compiles.
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.

◆ Current state
edina is a single-purpose Rcpp/Armadillo implementation of the Exploratory DINA model, feature-complete since its 2020 debut. Its entire visible surface — estimation plus Q-matrix comparison across k values — has not changed in five years. The only 2025 activity is a maintenance release that raises the R, Rcpp and RcppArmadillo floors so the package still compiles.
◆ Where it's heading
The gap between 0.1.1 and 0.1.2 is over five years, and 0.1.2 contains no modeling changes at all: dependency floors, a Makevars cleanup for newer Armadillo, a Quarto README, a CITATION fix for CRAN notes, and refreshed CI. This is custodial maintenance of a research artifact rather than active development. The same release landed across the maintainer's other packages the same morning — rrum got a near-identical body ten minutes earlier — which marks it as a lab-wide compatibility sweep, not an edina-specific push.
◆ Prediction
Expect the next release to be another compatibility bump triggered by an Armadillo or Rcpp change rather than new estimation features, on a similar multi-year cadence.
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.
