healthiar v0.2.6

• 11 September 2026

New features

• attribute_health() and attribute_lifetable() have the new argument main_results_by to quantify multiple exposure-outcome pairs at once. The dimensions named here (e.g. the info columns) are kept as separate rows in the main results instead of being summed.
• attribute_health() and attribute_lifetable() have the new argument threshold, now clearly distinguished from cutoff. The threshold is the anchor of the exposure-response function (subtracted from the exposure), while the cutoff truncates it.
• monetize(), cba() and get_inflation_factor() now accept year-specific inflation rates (a vector) and not only a constant rate.
• get_discount_factor() now returns one discount factor per value of n_years. Previously, only one value was returned for a vector of years.
• The info columns are now named after the names entered by the user (info_yourname) instead of info_column_1, info_column_2, etc.
• summarize_uncertainty() now shares the random draws across scenarios if seed is NULL, uses truncated (instead of reflected) draws for positive quantities, aggregates macro results from the totals of each simulation and supports the comparison of population impact fractions.

Bug Fixes

• The wrong results of attribute_lifetable() when time_horizon was different to the number of age groups have been corrected. Moreover, time_horizon = 1 produced a reversed sequence of years and max_age was ignored.
• The age groups are now sorted internally and validated (consecutive and of equal length), so that the order of the rows entered by the user does not change the results.
• The wrong behaviour of approach_newborns, silently ignored for deaths and single-year exposure, has been fixed with a warning.
• The wrong use of fraction_lived in prepare_lifetable() has been corrected.
• The wrong behaviour of multiexpose(), multiplying risks across all rows instead of within a row, has been fixed.
• Values of prop_pop_exp that do not sum up to 1 were silently renormalised. The equation in get_pop_fraction() has been corrected.
• In socialize(), the geographic units with a missing social indicator were assigned to the least deprived quantile. They are now dropped with a warning.
• Several defects in standardize() have been fixed (missing bhd_per_100k_inhab_std, wrong standardized exposure, missing grouping by uncertainty columns and wrong use of ref_prop_pop).
• The error “object exp_scen_1 not found” in compare() has been fixed, as well as the duplicated erf_eq in the labels.
• In daly(), the mis-named rate column that was then summed as an impact has been renamed to impact_per_100k_inhab.
• impact_per_100k_inhab was Inf if the population was 0. Now it is NA.
• The binning in prepare_exposure() dropped the extreme cells of the grid.
• prepare_mdi() aborted with a cryptic error if there was any missing value. Now missing values are handled and a warning is shown. Moreover, the results are now assigned and not lost.
• discount() showed an error when using its own documented default of discount_shape.
• monetize() did not keep real_growth_rate among the relevant columns.
• Entering two names in main_results_by was wrongly rejected.
• attribute_mod() did not tag the arguments with new values as entered by the user.
• health_outcome is now validated (error if NULL or not one of the options).
• More comprehensive validation of the input data: no exposure-response function data, increment equal to 0, missing erf_shape or rr_increment, non-consecutive age groups and inconsistent life table approaches in multiexpose().

Other improvements

• get_output() and the projection in attribute_lifetable() are now faster.
• The code has been streamlined overall: new internal function validate_args(), shorter and more consistent variable names, more code comments and removal of dead code.
• The data sets have been recompressed and the duplicated test data removed.
• Changes to prevent errors, warnings and notes in the CRAN checks, e.g.  requireNamespace() for suggested packages and tests skipped if a suggested package is not installed.

Documentation

• New vignette chapters on cut-off vs. threshold and on multiple exposure-outcome pairs.
• More extensive explanation of the differences between healthiar and AirQ+ in the life table approach.
• The pkgdown website is now built from the gh-pages branch, so the folder docs is not part of the master branch anymore.
• The badges of the website have been reorganized, the JOSS badge added and the Zenodo DOI moved to the new section “Stay updated”.
• A new acknowledgements section has been added.
• The presentation of healthiar at the ISEE conference is now available.
• The minimum R version in the readme file (4.2.0) is now consistent with DESCRIPTION.

Testing

• 26 fake examples in the tests have been replaced with real published studies.
• 71 additional internal tests. Now a total of 453 tests.

healthiar v0.2.5

• 11 August 2026

New features

• attribute_lifetable() and prepare_lifetable() now have the new argument fraction_lived to enter the fraction of year lived specific for each age group. Previously, 0.5 was internally fixed for all age groups.
• attribute_health() has been expanded to now accept the argument cutoff_ together with erf_eq_ in the absolute risk approach (consistent with relative risk risk). A warning is shown in this case because, for absolute risk, it is assumed that erf_eq_ already contains a cutoff.
• Fractional positive deaths and bhd values (with values between 0 and 1) are now allowed for lifetable calculations.
• The attributable deaths can now be quantifed with constant exposure in attribute_lifetable(). Previously, only possible with single year exposure.

Bug Fixes

• Error when installing the package without package dependences has been prevented.
• The wrong behaviour of erf_eq_lower and erf_eq_upper as string in attribute_health(), providing the same result for both, has been corrected.
• The wrong behaviour of socialize() providing deciles for other requested quantiles has been fixed.
• The wrong behaviour of get_paf() for categorical exposure distributions has been fixed.

Documentation

• Bugs in references of function descriptions and vignette have been fixed.
• More clear instructions on how to install the package has been provided.
• Contributing and a Code of Conduct files (sections in pkgdown web pages) have been created to provide information on how to interact with the community.
• The final version of paper published in the Journal of Open Source Software (JOSS) is now available.
• An updated citation of the package is now available refering to the JOSS paper.
• CITATION.cff has been added.
• The function descriptions and vignette have been updated to include instructions of new features.

Testing

• Additional internal tests were added. Now a total of 382 tests.

healthiar v0.2.4

• 12 March 2026

Bug Fixes

• Previously, monetize() used the argument inflation_factor for both adjusting discount_rate and increasing value overtime. This has been resolved by introducing a new argument called real_growth_rate.
  Now, inflation_rate is used exclusively for adjusting discount_rate, while real_growth_rate handles value growth overtime.

Other improvements

• get_discount_factor() previously had inflation_rate as argument. Now, not anymore to keep different concepts separated.
• get_inflation_factor() previously had discount_rate as argument. Now, not anymore to keep different concepts separated.

healthiar v0.2.3

• 19 February 2026

New features

• Using compare() after standardizing results from attribute_health() now works
• For the sub-group analysis, exposure value can be specific for each geo_id_micro AND info column
• The argument social_indicator and geo_id_micro in socialize() can now use tidy data
• monetize() works after compare()

Bug Fixes

• Using socialize() and standardize() without ref_prop_pop now works properly
• Now attribute_lifetable() allows all lengths for age group (before, only 100 age categories were allowed)
• The data validation now identifies correctly whether the argument n_years was entered by the user or not

Testing

• 31 additional internal tests

Other improvements

• The argument n_years has no default value anymore in monetize() and discount()
• Error message if monetize() is used after compare() with different year of analysis or baseline health data in the two scenarios (not attributable to policy intervention)
• More complete warning message if absolute risk and cutoff is provided
