genderBR vs volcalc
A side-by-side editorial comparison of genderBR and volcalc — release velocity, themes, recent moves, and the top alternatives to consider.
genderBR vs volcalc: at a glance
What is genderBR?
A census lookup table learns to guess names it has never seen.
genderBR infers gender from Brazilian first names, and until this year it did so purely by looking names up in IBGE census frequency data. Version 1.3.0 adds a second, learned path: a character-level neural network that scores names the census never recorded. The package now carries torch as a hard dependency and pulls model weights from Hugging Face on first use.
What is volcalc?
Rebuilt itself around SMILES and .mol input, then made the chemistry configurable
volcalc estimates the volatility of chemical compounds from their structure, implementing the SIMPOL.1 group-contribution method and the Meredith et al. variant. Version 2.0.0 severed the package from KEGG: calc_vol() takes .mol file paths or SMILES strings directly, is vectorized over multiple compounds, and the group-contribution maths was split into its own simpol1() function. Work since has been chemistry accuracy and configurability — the full set of SIMPOL.1 functional groups, volatility thresholds for clean atmosphere, polluted atmosphere or soil, user-supplied temperature, and a validate option returning NA when structure parsing looks suspect.

A census lookup table learns to guess names it has never seen.
◆ Current state
genderBR infers gender from Brazilian first names, and until this year it did so purely by looking names up in IBGE census frequency data. Version 1.3.0 adds a second, learned path: a character-level neural network that scores names the census never recorded. The package now carries torch as a hard dependency and pulls model weights from Hugging Face on first use.
◆ Where it's heading
The arc is from data lookup to inference. 1.2.0 modernised the lookup side by adding 2022 census data and swapping the dplyr join layer for data.table; 1.3.0 keeps that intact and bolts a model beside it rather than replacing it. The maintainer is also cleaning up platform-dependent string handling and deprecating the encoding argument, which suggests consolidation around the new code path.
◆ Prediction
Expect the deprecated encoding argument to be removed and the neural path to gain the threshold-tuning controls the census path already has. Whether get_gender_nn() becomes the default is the open question the release notes do not answer.

◆ Current state
volcalc estimates the volatility of chemical compounds from their structure, implementing the SIMPOL.1 group-contribution method and the Meredith et al. variant.

Work since has been chemistry accuracy and configurability — the full set of SIMPOL.1 functional groups, volatility thresholds for clean atmosphere, polluted atmosphere or soil, user-supplied temperature, and a validate option returning NA when structure parsing looks suspect.
◆ Where it's heading
The arc runs from a script tied to one database toward a general structure-to-volatility tool. Dropping KEGG from the core in 2.0.0, then removing KEGGREST as a dependency entirely in 2.2.0, took the package from volatility for KEGG compounds to volatility for any structure a user can supply. The accompanying manuscript published in 2023, and the changelog since has been careful about coefficient double-counting — amines and amides have each been corrected — which suggests the group definitions are the part under active scrutiny.
◆ Prediction
The smarts_simpol1 dataset added in 2.2.0 documents how functional groups are defined, pointing toward further estimation methods alongside SIMPOL.1 and Meredith; splitting simpol1() out in 2.0.0 was stated to be groundwork for exactly that.
