tabNew(names, levels, values, normalize = "none", smooth = 0)
names 
Names of variables defining table; a character vector or a right hand sided formula. 
levels 

values 
values to go into the parray 
normalize 
Either "none", "first" or "all". Should result be normalized, see 'Details' below. 
smooth 
Should values be smoothed, see 'Details' below. 
If normalize="first"
then for each configuration of
all other variables than the first, the probabilities are
normalized to sum to one. Thus f(a,b,c) becomes a conditional
probability table of the form p(ab,c). If
normalize="all"
then the sum over all entries of
f(a,b,c) is one.
If \code{smooth} is positive then \code{smooth} is added to \code{values} before normalization takes place.
An array.
