split_timeDF_by_intervals {timeDF}

Function to split timeDF into a list by regular intervals

Description

split_timeDF_by_intervals splits timeDF into a list of timeDF objects by regular intervals. Intervals can be spcified by numeric value and its unit. For example, if the interval is specified as two days, timeDF object is split by two day interval. The start time for this interval is decided by the minimum time and the interval unit in the original timeDF. If there are no records present for some intervals, their corresponding results are timeDF objects with zero rows.

Usage

split_timeDF_by_intervals(timeDF,byN,byUnits,
                          modStart=0,modEnd=0,modUnits = "auto")

Arguments

timeDF

timeDF object

byN

interval value, numeric

byUnits

interval unit, "days", "hours" or "mins"

modStart

values to be added for starts of intervals

modEnd

values to be added for ends of intervals

modUnits

units for values of modStart and modEnd

Value

list of timeDF objects
