R does not allow 'gaps' in its class "ts".
Irregular time series are covered in several packages, including tseries,
its and zoo.

I like the fact that in subtracting two time series objects that there
is some effort to align the series. So if I have a time series of that
begins at 1 and one that begins at 2 a subtraction operation makes sure
that the proper values are subtracted. But I am unclear as to the best
way to build a time series with "holes". say that I have data for "day"
1,2,6,7 in one time series and 1,2,3,4,5,6,7 in another. How do I
construct the time series and indicate the missing data for 3,4,5 as in
the first series? Eventually I would like to find the difference between
the two series. If the difference is series 2 minues series one, then
for the indexes of 3,4,5 in the resultant difference it would just be
the series 2 value. The resultant series would have a length of 7.
Thank you.
