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.
Minor change to description in DESCRIPTION and correction of year for most recent paper (2025).
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.
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.
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.
alfam2() function now checks that all
pass.col are in the dat data frame (see issue
#92).
Fix a phantom incorporation effect on the r3 parameter that could show up with inconsistent user inputs (see issue #87).
A NEWS.md file (this file) has been added.
conf.int in the alfam2() function
no longer returns incorrect message about user-defined parametersconf.int = 'all' the alfam2()
