[R-SIG-Finance] Concatenating time series objects?

[Marc Delvaux]

I am trying to do an incremental download of time series financial
data, with say 5 new points every time I do an download.  I am trying
to find a simple way to perform concatenation but I cannot seem to
find an easy way to do that.  I did find a way using
xts(c(coredata(seq1),coredata(seq2)),
order.by=c(time(seq1),time(seq2))), but this loses some information
that was present in seq1, and I was thinking there should be a simpler
way.
