softwareRisk 0.2.0 (2026-04-04)
Breaking changes
risk_form_variance_share_fun() has been removed. Its functionality is fully
subsumed by uncertainty_fun(), which already computed identical Sobol' sensitivity
indices for all four parameters as part of its output. Users should call
uncertainty_fun() directly and read the sensitivity_analysis list-column from
$nodes.
- Removed the
risk_form argument from all_paths_fun() and uncertainty_fun().
The additive formula (risk_form = "additive") is now subsumed by the unified
power-mean formula with p = 1 (default).
uncertainty_fun() now returns tibbles instead of data.table objects. The
data.table package is no longer a dependency.
Bug fixes
- Fixed duplicate
"p" column bug in Sobol sample matrices within uncertainty_fun().
The raw column from sobol_matrices() is now named "p_raw" internally so the
rescaled p column is correctly used.
- Added
@importFrom rlang %||% to plot_top_paths_fun() (previously not imported).
- Added missing
@importFrom declarations for ggplot2::scale_fill_viridis_c,
ggplot2::geom_tile, stats::setNames, ggplot2::geom_errorbar,
ggplot2::geom_point, and scales::breaks_pretty.
- Fixed fallback
nodes_tbl in plot_top_paths_fun() that was missing risk_score.
The function now requires all_paths_out to be the output of all_paths_fun().
- Fixed
\deqn{[0, 1]} in @param of plot_top_paths_fun().
Improvements
uncertainty_fun() now returns Sobol' sensitivity indices labelled alpha,
beta, gamma, and p in the sensitivity_analysis list-column of $nodes,
replacing the previous internal raw labels a_raw, b_raw, c_raw, p_raw.
Internally the Sobol' design still draws four independent U(0,1) values (required
by the quasi-random sequence); the raw draws are normalised to weights and mapped to
p ∈ [−1, 2] before the model is evaluated. The documentation explains this
in a dedicated Parameter labels and the Sobol' design section.
slope_fun() now uses an analytic OLS formula instead of stats::lm().
- Removed the internal
slope_per_draw_from_nodes closure in uncertainty_fun() and
replaced it with calls to slope_fun().
- Added shared input-validation helper
validate_all_paths_out() used across
multiple functions.
- Added
eps parameter to uncertainty_fun() for forwarding to the risk evaluation.
- Corrected
@return documentation for path_cc in all_paths_fun().
- Updated
inst/CITATION to version 0.2.0.
- Removed
NAMESPACE.bak.
- Removed redundant
!is.na(x) guard in slope_fun() and gini_index_fun().
- Replaced three sequential
vapply loops in path_uncertainty_plot() with a single pass.
- Removed trailing blank lines in
all_paths_fun.R.
- Added
testthat test suite with tests for slope_fun, gini_index_fun,
all_paths_fun, and uncertainty_fun.
