mltools 0.3.3

• 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

• 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

mltools 0.3.1
