Not my domain, but you will more than likely have to aggregate to some
sort of regular/homogenous type of series for most traditional tools
xts has to.period to aggregate up to a lower frequency from tick-level
data. Coupled with something like na.locf you can make yourself some
high frequency 'regular' data from 'irregular'
Regular and irregular of course depend on what you are looking at
(weekends missing in daily data can still be 'regular').
I'd be interested in hearing thoughts from those who actually tread in
the high-freq domain...
A wealth of information can be found here:
