Or to put it another way, as I said before, ts() in R is incompatible
with ts() in S, and the name has already been taken for the constructor
of the R ts class. (In case you still do not get it, there is already
an R ts class.) Do you want us to change ts in R not to be the constructor
of the ts class, and thereby `break a lot of user code' in R?
