- Added unit tests
- Support for multiclass mcc() and user may now provide a confusion matrix as input
- Avoid calling utils::modifyList() on POSIXlt objects
mltools 0.3.4 (2017-12-05)
- Added and organize evaluation metrics, mean square error: mse(), mean square logarithmic error: msle(), root mean square error: rmse(), and root mean square logarithmic error: rmsle(). Each metric now includes an option to pass weights and ignore NA values.
- Added unit tests
mltools 0.3.3 (2017-09-12)
- In
date_factor(dateVec, ...) fixed bug in "character string is not in a standard unambiguous format" produced by some date values
mltools 0.3.2 (2017-08-28)
- In
folds(x, ...) x can now be a positive integer specifying the number of fold IDs to generate
- In
date_factor(dateVec, ...) the argument fullyears has been dropped and replaced by the more flexible pair of arguments minDate and maxDate for determining resulting vector levels. Additionally a bug regarding type=yearquarters has been fixed.
- In
bin_data() added some input validation

date_factor() occuring when type = "yearquarter" and fullyears = FALSE
- Fixed bugs involving unsorted or duplicate ubounds in
empirical_cdf()
mltools 0.2.0 (2017-01-03)
- Added
date_factor() for converting dates to a grouped ordered factor (e.g. months, yearmonths, yearquarters, etc.)
