timetools:Seasonal/Sequential (Instants/Durations, Even or not) Time
Series
Objects to manipulate sequential and seasonal time series. Sequential time series based on time instants and time duration
are handled. Both can be regularly or unevenly spaced
(overlapping duration are allowed). Only POSIX* format are used
for dates and times. The following classes are provided :
'POSIXcti', 'POSIXctp', 'TimeIntervalDataFrame',
'TimeInstantDataFrame', 'SubtimeDataFrame' ; methods to switch
from a class to another and to modify the time support of
series (hourly time series to daily time series for instance)
are also defined. Tools provided can be used for instance to
handle environmental monitoring data (not always produced on a
regular time base).
