The values of
x are repeated for each combination
of elements in the vectors supplied via

elements of each vector in

second elements as another set, and so on.
x is repeated for
each of these sets.
numeric; vector of data points which are to be replicated
for each of the sets of vectors supplied to
additional vector arguments to be expanded to the correct
length. These are taken to be a set of values to be replicated for
each of the elements of
a matrix of replicated vectors, with column names for
and named arguments passed as
