Hello,
I've a time series, T, for an irregular sequence of days (data for bank
holidays weekends have been removed). I would like to aggregate this series
by into weeks using
aggregate(x, by="weeks", FUN=mean).
To do this, I think that x needs to be a timeSeries object, and when I try
to call
timeSeries(data=T, positions=irregular.sequence.of.days)
I get lots of NAs in the resulting object. (Note: I've checked that
length(T)=length(irregular.sequence of days). My dates are of the form
dd/mm/yyyy in case it's relevant.)
Thanks in advance!
