• Documentation update

splitTools 0.3.3

New Functionality

• Sometimes, one need to stratify on multiple columns. The new function multi_strata() provides a vector of stratification groups based on a data frame that can be then passed to partition() or create_folds(). Each stratification group will contain "similar" data rows, where similarity is either based on a kmeans cluster analysis or forming all combinations of binned columns. Thanks to kapsner for the idea and the help with the implementation.

Maintenance

• Set up github actions, thanks to L. Kapsner.

splitTools 0.3.2

This is documentation and maintenance update only with the following changes:

• Updated documentation to clarify that create_folds() creates in-sample indices by default. If out-of-sample indices are to be generated, set invert = TRUE.
• Got rid of a CRAN check notes about LazyData.
• Changed to better way of updating/generating the package.
