forestTIME vs volcalc
A side-by-side editorial comparison of forestTIME and volcalc — release velocity, themes, recent moves, and the top alternatives to consider.
forestTIME vs volcalc: at a glance
What is forestTIME?
A forest-inventory pipeline grew the strata machinery it needs to make population estimates.
forestTIME turns US Forest Inventory and Analysis data into annualized carbon and biomass estimates by interpolating between the years each plot is actually measured. Version 2.2.0 adds fia_assign_strata(), which matches every plot-year to an EVALID, estimation unit and stratum along with the values needed for population-level estimation with variance. The composite ID scheme also changed order, which breaks joins written against the old one.
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 forest-inventory pipeline grew the strata machinery it needs to make population estimates.
◆ Current state
forestTIME turns US Forest Inventory and Analysis data into annualized carbon and biomass estimates by interpolating between the years each plot is actually measured. Version 2.2.0 adds fia_assign_strata(), which matches every plot-year to an EVALID, estimation unit and stratum along with the values needed for population-level estimation with variance. The composite ID scheme also changed order, which breaks joins written against the old one.
◆ Where it's heading
The arc runs from a duckDB-backed script to a package with a design-based estimation story. First the database layer was removed in favour of a single interpolated table; then the function surface was consolidated behind fia_ names and fia_annualize(); then expansion factors appeared; now the stratification the FIA estimators actually require. Each step moves closer to producing estimates users can put an error bar on rather than interpolated numbers.
◆ Prediction
The notes name a temporary workaround for woodland species, whose carbon and biomass code is missing, and say fia_estimate() will eventually handle them directly. That, plus variance calculation built on the new strata columns, is the visible next work.

◆ 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. 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.
◆ 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.
