Please find below the package announcement for the R package lubridate available from cran. Thank you, Garrett Grolemund Rice University ##lubridate Date-time data can be frustrating to work with in R. R commands for date-times are generally unintuitive and change depending on the type of date-time object being used. Moreover, the methods we use with date-times must be robust to time zones, leap days, daylight savings times, and other time related quirks, and R lacks these capabilities in some situations. Lubridate makes it easier to do the things R does with date-times and possible to do the things R does not. Specifically, lubridate provides: * a set of intuitive date-time related functions that work the same way for all common date-time classes (including those from?chron, timeDate,?zoo,?xts,its,?tis,?timeSeries,?fts, and?tseries) * quick and easy parsing of date-times:?ymd(),?dmy(),?mdy(), ... * simple functions to extract and modify components of a date-time, such as years, months, days, hours, minutes, and seconds:?year(), month(),?day(), ... * helper functions for handling time zones:?with_tz(),?force_tz() Lubridate also expands the type of mathematical operations that can be performed with date-time objects. It introduces three new time span classes borrowed from http://joda.org. * durations, which measure the exact amount of time between two points * periods, which accurately track clock times despite leap years, leap seconds, and day light savings time * intervals, a protean summary of the time information between two points _______________________________________________ R-packages mailing list R-packages at r-project.org https://stat.ethz.ch/mailman/listinfo/r-packages
