NEWS for ALFAM2 R package

ALFAM2 v4.2.14 (5 Dec 2025)

Bug fixes

From v4.2 alfam2() could be run without TAN application rate, but this did not work when the conf.int argument was used. That problem was fixed.

Documentation

Minor change to description in DESCRIPTION and correction of year for most recent paper (2025).

ALFAM2 v4.2 (8 Nov 2024)

Parameter correction

The latest default parameter set was revised slightly to reflect new results after making corrections to the parameter estimation procedure. Resulting predictions will be slightly different than in v4.1.11 and earlier. In some cases the change may be around 1% of applied TAN, but is typically smaller.

New feature

The alfam2() function can now be run without a column for TAN applcation rate (app.name argument). If omitted (or if default argument name is not present) only relative emission will be returned with a warning.

Documentation

Available default parameter sets are now documented in a separate help file. View it with ?alfam2pars or ?alfam2pars03 etc.

A new paper describing recent developments in the package has been published and is now listed in the help files and vignette.
