TVECTOR(x;s;p) copies the values from table
t into a variate. The scalar
s is zero if the margins of the table are to be omitted, or a non-zero (and non-missing) value if they are included. The pointer
p contains the classifying factors of the table, defining the order in which the values are to be copied; this can be omitted if
t is a one-way table. If margins are not to be included from a one-way table,
s can also be omitted.
