origami 1.0.8 (2026-05-18)

• Updates to CRAN maintainer.
• Fixes testing bug checking that multicore evaluation is not significantly slower than sequential as detected by CRAN automated checks.

origami 1.0.7 (2022-10-19)

• Removal of unused import future::values given its deprecation.

origami 1.0.6

• Fixes to stratified cross-validation bugs.
• More informative warnings when n (sample size) is less than or equal to V (number of folds).

origami 1.0.5 (2021-09-28)

• Addition of glmnet to package Suggests since used in the vignette.
• Resolve issue stemming from the partial matching of argument names (https://github.com/tlverse/origami/issues/56) by specifying throughout.

origami 1.0.4

• Fix the incorrect use of future.apply by including future.seed = TRUE, as per https://github.com/tlverse/origami/issues/48.
• Fixes to folds_rolling_origin_pooled and folds_rolling_window_pooled, as per https://github.com/tlverse/origami/pull/50.
• Sped up all pooled time-series fold functions with lapply.
• All pooled time-series fold functions (folds_rolling_origin_pooled, folds_rolling_window_pooled, folds_vfold_rolling_origin_pooled, folds_vfold_rolling_window_pooled) now allow for variability in the number of observations for each independent unit (i.e., the subject).
• Added test for pooled time-series cross-validation with multi-unit time-series to test the update above. In this test, the total number of observations and the time-points for which there are observations varies across the units.

origami 1.0.3 (2020-01-16)

• A maintenance release addressing reported issues, including changes to unit tests that relied on Suggested packages dependencies.

origami 1.0.2

• Adds new functionality for cross-validation with time-series, especially functionality for pooling time-series data. This includes the new functions folds_rolling_origin_pooled, folds_rolling_window_pooled, folds_vfold_rolling_origin_pooled, folds_vfold_rolling_window_pooled.

origami 1.0.1 (2019-05-01)

• Adds a simple check of the current R version in the unit tests in the file tests/testthat/test-overall.R to use appropriate hard-coded values that depend on the R version. Note that these differ between R < 3.6.0 and R > 3.6.0 due to an important change in the default PRNG.

origami 1.0.0 (2018-03-06)

• Adds a new function folds2foldvec for easy conversion between the folds structure used by origami and other packages (e.g., glmnet).
• Adds an option to use lapply instead of future_lapply, for compatibility with other packages in a custom parallelization framework.
• Calls future_lapply from the new more modular package future.apply rather than from future, matching the author's recommendation.

origami 0.8.0 (2017-06-23)

• First CRAN release.
• Removed origami_SuperLearner functionality temporarily.
