| fillup {hyper2} | R Documentation |
Function fillup() concatenates a vector with a ‘fillup’
value to ensure a unit sum; if given a matrix, attaches a column so
the rowsums are 1.
Function indep() is the inverse: it removes the final element
of a vector, leaving only an independent set.
fillup(x,total=1) indep(x)

Numeric vector |
total |
Total value for probability |
Usually you want the total to be one, to enforce the unit sum
constraint. Passing total=0 constrains the sum to be
zero. This is useful when considering dp; see the
example at gradient.Rd.
