parental: Constructor function for a 'parental' object.

In rjbgoudie/parental: Light-weight graph package

Description

Objects of class parental are lists with the ith component specifyingthe parents of node i. The parents must be specified as a vector of integers – the storage.mode() of these integers MUST be integer. If the node has no parents, use integer(0).

Usage

  parental(...)

Arguments

...	A series of vectors specifying the parents of each node. These vectors must be of storage.mode "integer".

Details

Note, in particular, that list(2, 1) would not be a valid parental object, because storage.mode(2) and storage.mode(1) == "double". Instead one would use list(2L, 1L), as documented in the R FAQ (see [1])

Parents of each node MUST be sorted in increasing order. Conformance with object requirements can be tested by is.valid()
