%description
Basic time series functionalities such as listing of missing values,
application of arbitrary aggregation as well as rolling (asymmetric)
window functions and automatic detection of periodicity. As it is mainly
based on 'data.table', it is fast and (in combination with the 'R6'
package) offers reference semantics. In addition to its native R6
interface, it provides an S3 interface for those who prefer the latter.
Finally yet importantly, its functional approach allows for incorporating
functionalities from many other packages.
