FuzzyHits Class

The FuzzyHits class extends the Hits class to represent hits that are associated with different grades of membership in the interval [0,1].

FuzzyHits(from = integer(0), to = integer(0),
  membership = numeric(0), nLnode = 0L, nRnode = 0L, ...)

Arguments

from, to	Two integer vectors of the same length. The values in from must be >= 1 and <= nLnode. The values in to must be >= 1 and <= nRnode.
membership	Numeric. Vector of numeric membership function in the range [0,1]
nLnode, nRnode	Number of left and right nodes.
...	Arguments metadata columns to set on the FuzzyHits object. All the metadata columns must be vector-like objects of the same length as from, to, and membership.

Value

A FuzzyHits object.

Details

This class does not define any additional slot to the Hits class. However, this class defines additional validity checks to ensure that every relation stored in a FuzzyHits are associated with a numeric membership funtion in the interval [0,1].
