Hi Vito,
Short answer: argument 'start' can take any value you want. For monthly
observations (the case 'ts()' handles most nicely, with quarterly
observations), 'start' will be used to specify the year and month (or
quarter) of the first observation.
From what I can gather from the help
I find complete.cases() to be very useful for this kind of stuff (and
very fast). As in,
