In parttime: Partial Datetime Handling

parttime 0.1.2

Minor updates to documentation to handle new R CMD check NOTEs.

parttime 0.1.1

Update formals for vctrs generic methods to reflect changes in the vctrs package.

parttime 0.1.0

Reworked pmax and pmin handling to address edge case failure modes. Performance may be impacted. If you identify performance regressions that impact your work, please file a ticket. (#35, @dgkf)
Renamed parse_iso8601 to parse_iso8601_datetime to prepare for introduction of an alternative parser for iso8601 timespans. (#38, @dgkf)
New format added for CDISC-style datetime strings. Can be used via as.parttime(..., format = parse_cdisc_datetime). (#38, @dgkf)
as.parttime will now, by default, show warnings when some strings fail to parse into the provided format. Behavior can be configured using the new on.na parameter. (#36, @dgkf)
extends lubridate-style accessor and assignment helpers, such as year() and year()<-. Unfortuntely, many are provided as S4 generics, and may be masked by other packages that extend these generics. Some generic-like functions are provided only as non-generic forms in lubridate and will always be masked, such as tz(). (#14, @dgkf).
added format parameter to as.parttime, allowing for custom regular expressions or functions to be used to parse non-iso formats. If other established standards are regularly needeed, they could be included with the package. (#13, @dgkf)
added res ("resolution") parameter to the impute_* family of functions, allowing for only some field up until the provided resolution to be imputed. With this, also added impute_date_* alternatives which default to imputing to a "day" resolution. (#12, @dgkf)
rename is_partial_* to has_partial_* to avoid ambiguity with class checks
removed some deprecated pillar interfaces
bring package up-to-speed with vctrs package changes from last few years
fixed subset assignment operators [<- and [[<-
improved imputation as to not introduce dates that aren't viable for the given month

parttime 0.0.1
