Hello, I do not think lubridate is fast, It just acts as a syntax sweetener.
Here is the description of the package by its author : Quote: Lubridate makes it easier to work with dates and times by providing functions to identify and parse date-time data,extract and modify components of a datetime (years, months,days, hours, minutes, and seconds), perform accurate math on date-times, handle time zones and Daylight Savings Time. Lubridate has a consistent, memorable syntax, that makes working with dates fun instead of frustrating. As far as I know no package provide a quickest datetime handle, even if data.table proposes IDate, ITime... that stores integer for fast sorting. (Problem is for me that it does not support sub-second but we spoke about it already) If any package provides a faster implementation for datetimes I'll be glag to hear about it. -- View this message in context: http://r.789695.n4.nabble.com/Error-in-a-package-that-imports-data-table-tp4660173p4660598.html Sent from the datatable-help mailing list archive at Nabble.com. _______________________________________________ datatable-help mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/datatable-help
