Changes in version 0.2.1 (2026-07-21) Reproducibility - Add torch_seed to ria.test.control() to control Torch neural-network initialization and dropout independently of R's random-number generator. - Delay Torch device initialization until after R-randomized estimation steps, so first-use Torch initialization cannot change cross-fitting or Z-prime folds. Changes in version 0.2.0 Breaking changes - Restrict estimation to natural effects, randomized interventional analogues, and the TE - TE^R falsification test. - Replace effect with estimand = "test", "natural", or "ria"; the test is now the default. - Align returned estimand names with the paper and remove nuisance fits from the returned object. Changes in version 0.1.3 Bug fixes - Synced fold construction and influence-function identifiers with upstream fixes. Changes in version 0.1.2 Bug fixes - Fixed a bug caused by upgrading to S7 0.2.0. Changes in version 0.1.0 General - Initial CRAN submission. - Uses ife for storing effect estimates.
