An R object that contains information on UniProtKB KeyWords terms. These terms are organised as a direct acyclic graph (DAG), which is further stored as an object of the class 'igraph' (see http://igraph.org/r/doc/aaa-igraph-package.html). UniProtKB KeyWords (KW) controlled vocabulary provides a summary of the entry content and is used to index UniProtKB/Swiss-Prot entries based on 10 categories (the category "Technical term" being excluded here).
onto.KW <- dcRDataLoader(RData = "onto.KW")
an object of S4 class Onto. It has slots for "nodeInfo" and "adjMatrix"
nodeInfo: an object of S4 class InfoDataFrame, describing information on nodes/terms including: "term_id" (i.e. Term ID), "term_name" (i.e. Term Name), "term_namespace" (i.e. Term Namespace), and "term_distance" (i.e. Term Distance: the distance to the root; always 0 for the root itself)
adjMatrix: an object of S4 class AdjData, containing adjacency data matrix, with rows for parent (arrow-outbound) and columns for children (arrow-inbound)
