⚠️There's a newer version (1.15.3) of this package.Take me there.

timetools (version 1.5.2)

provides objects and tools to manipulate irregular heterogeneous time data and subtime data.

Description

This package is intended to manipulate irregular time series such as subtime series, series based on time intervals, etc. This package uses only POSIX* format. Main things defined in this package are the classes POSIXcti, POSIXctp, TimeIntervalDataFrame, TimeInstantDataFrame, SubtimeDataFrame, methods to switch from one class to another and the changeSupport method for TimeIntervalDataFrame.
