Ragged time series data
...ts together, but with the method I use I end up losing the corresponding
time of day information.
This is what I have done so far
data=*vector of integers
*hours= *"character" vector of times %H:%M:S% *
days= *"character" vector of dates %m/%d/%Y
*
hr.days=paste(days,hours)
hr.dayslt=as.POSIXlt(strptime(hr.days, format="%m/%d/%Y %H:%M:%S"))
tapply(data,hr.dayslt$yday,max)
This works to give me the counts I want corresponding to a Julain day, but
it does not tell me which hour corresponds to each daily maximum. Is
tapply() the wrong route?
