rbridge 1.0.4
- Apply the same Armadillo OpenMP configuration to all C++ translation
units, including the generated Rcpp wrappers. This fixes the
inconsistent sparse matrix type definitions reported by CRAN’s GCC
link-time optimization check.
- Preserve explicit parallelism across cross-validation folds, with
sequential Armadillo operations inside each fold. Estimation methods,
numerical kernels, public interfaces and defaults are unchanged.
rbridge 1.0.3
- Restore default prediction and coefficient extraction on current R
versions.
- Path objects return the full coefficient or prediction path when
s is omitted. Numeric s selects exact fitted
lambda values. For path objects, s = "lambda.min" selects
the smallest fitted lambda; lambda.1se requires CV.
- Forward
num_threads and converge from
cross-validation wrappers, and honor the supplied initial
converge value in the solver. The default is
unchanged.
- Reject nonfinite data, constant predictors, invalid penalty
parameters, invalid fold counts and incompatible restriction dimensions
before fitting.
- Replace deprecated Armadillo scalar conversion and remove obsolete
C++11 requests. Reuse the fixed design cross-product in the restricted
solver.
- Update authorship, dependencies, published article citation and
documentation.
- Cache fixed and active-set cross-products in both solvers. Solve the
restricted bridge and restriction right-hand sides together instead of
repeating matrix inversions. Singular or numerically unresolved systems
now fail explicitly; no automatic approximate solution is
substituted.
- Reuse CV data slices and compute prediction paths in one matrix
multiplication. Request portable OpenMP flags where available, with a
sequential fallback. Report the installed build capability with the
additive
rbridge_info() API. Worker failures are propagated
after threads finish.
- Add 36 frozen synthetic regression cases, independent
constrained-ridge and uneven-fold CV checks, thread consistency tests
and locally built guides.
- Document a completed 96-shard synthetic benchmark with 48 passing
numerical comparisons. Casewise median speed ratios are 3.14x for
bridge, 2.59x for rbridge, 2.99x for cv.bridge and 2.57x for cv.rbridge
against the first repaired candidate. Reported ratios are limited to the
recorded designs and environment.
- Preserve the historical solver, lambda grid, folds, thresholds and
the standardized coefficient scale used for restrictions. Returned
coefficients remain on the original predictor scale.
