fillup function

Fillup function

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,H=NULL,total=1)
indep(x)

Arguments

• x: Numeric vector
• H: Object with pnames() attribute, typically of class hyper2 or hyper3, used for names if supplied
• total: Total value for probability

Details

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.
