I suspect, but have not tested, that your src$date element has class
"POSIXlt", which is internally a list, in which case splitting by it might
not work properly, and might be the cause of your out of bounds error
message.
One of these might do the job:
src$date <- format(strptime(tickdata$da
You could try using the numeric representation of date, and split the data
frame using that variable. For example:
src$date.num <- as.numeric(src$date)
