enderecobr vs MultiSpline: at a glance
What is enderecobr?
Brazilian address standardisation moves its core to Rust, betting on throughput over pure R
enderecobr standardises Brazilian address fields — street types, neighbourhoods, states, postcodes, house numbers — into consistent forms so records from different registries can be compared. It comes out of the ipeaGIT ecosystem and its API is a family of padronizar_* functions plus one padronizar_enderecos() that runs them together. The 0.5.0 release rewrote those standardisation functions in Rust with a documented speedup.
What is MultiSpline?
MultiSpline went from five functions to a full multilevel spline framework in seven weeks.
MultiSpline fits spline-based nonlinear models to multilevel and longitudinal data in R. The package reached CRAN in February 2026 with five functions covering fitting, summary, prediction, plotting and intraclass correlations. Version 0.2.0, seven weeks later, adds cross-classified and nested random-effect structures, automatic knot selection, a multilevel R-squared variance partition, derivative-based interpretation with turning points, model comparison against polynomials, and cluster heterogeneity analysis, while keeping every 0.1.0 call valid.

Brazilian address standardisation moves its core to Rust, betting on throughput over pure R
◆ Current state
enderecobr standardises Brazilian address fields — street types, neighbourhoods, states, postcodes, house numbers — into consistent forms so records from different registries can be compared. It comes out of the ipeaGIT ecosystem and its API is a family of padronizar_* functions plus one padronizar_enderecos() that runs them together. The 0.5.0 release rewrote those standardisation functions in Rust with a documented speedup.
◆ Where it's heading
Two years of releases were about control and correctness: new formato arguments letting callers choose state names or abbreviations, integers or characters for house numbers, and a run of fixes for numbers mangled by thousands separators. That work settled the semantics. With the behaviour pinned down, the Rust rewrite becomes the natural next move, and the release pairs it with new matching rules for the two messiest fields, neighbourhoods and street names.
◆ Prediction
The rewrite covers the standardisation functions specifically, so the remaining pure-R paths around them are the likely next targets, alongside continued rule additions for street and neighbourhood variants.

0.0ANALYTICS
MultiSpline went from five functions to a full multilevel spline framework in seven weeks.
◆ Current state
MultiSpline fits spline-based nonlinear models to multilevel and longitudinal data in R. The package reached CRAN in February 2026 with five functions covering fitting, summary, prediction, plotting and intraclass correlations. Version 0.2.0, seven weeks later, adds cross-classified and nested random-effect structures, automatic knot selection, a multilevel R-squared variance partition, derivative-based interpretation with turning points, model comparison against polynomials, and cluster heterogeneity analysis, while keeping every 0.1.0 call valid.
◆ Where it's heading
The arc is a research package being built out into a workflow at speed: 0.1.0 could fit a curve, 0.2.0 can tell you where the curve turns, how much variance each level explains, and whether a spline beats a polynomial at all. Backward compatibility was preserved across that expansion, which suggests the author is building for outside users rather than a single paper. The JOSS submission referenced in 0.1.1 points at academic distribution as the intended channel.
◆ Prediction
With the interpretation and diagnostics layers now in place, the next release will most likely extend the supported model families beyond the current lmer and glmer backends.
