As far as I know, no such function exists in R, but
it would be totally trivial to write one, if that's
what you really want.
However the question you pose makes little sense to me. If
you really have a ``statisical model'' then there must be
some marginal distribution for each of the probabilities (I
*assume* They are probabilities) going into the sequence
which you wish to sum to 1.
You mention no such distribution.
To generate such a sequence with an arbitray marginal
distribution is so trivial that it does not bear discussing.
If you really can't see how to do this, then you probably
shouldn't be messing about with ``statistical models''.
You did not explicitly deny that this is a homework problem.
I still suspect that it is.
cheers,
Rolf Turner
