4DModeller review
A focused R toolkit for Bayesian spatio-temporal models, meshes and model assessment.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
4DModeller is an open-source R package with companion Shiny apps and tutorials for building spatially distributed, temporally dependent statistical models. It is aimed at specialists who need Bayesian hierarchical modeling with INLA and inlabru, particularly when their data combines spatial coordinates, time indices and measured values. The package is available for Linux, Windows and macOS, and its workflows cover mesh construction, model setup, visualization and assessment.
Its strongest fit is the connected modeling workflow: users can build finite-element meshes, specify priors and hyperparameters, and evaluate models within the same specialized toolkit. Companion Shiny apps provide tools for mesh building and model creation, while tutorials walk through examples involving COVID-19, hydrology and ocean heat content. This makes 4DModeller more relevant to spatial and temporal modeling work than to broad statistical analysis; people seeking a general-purpose analysis environment may prefer a wider-ranging tool.
The package is openly available under GPL (>= 3), with an open-source pricing model and a free plan. It integrates with INLA, inlabru and R, and deployment is described as both desktop and cloud. Documentation is the listed support channel, so buyers should be comfortable learning from written guidance and tutorials. Choose 4DModeller when its INLA/inlabru-centered approach and mesh tools match the modeling problem; look elsewhere if the priority is general statistical software or a different support model.
4DModeller pros and cons
- Where it wins

- Includes finite-element mesh, prior and hyperparameter tools
- Pairs R workflows with Shiny apps and applied tutorials
- Where it doesn't
- Focused on spatio-temporal modeling rather than general statistical analysis
- Workflows expect tabular data with coordinates, time indices and values
- Documentation is the listed support channel
