Annotations of Rfam RNA families by Gene Ontology Cellular Component (GOCC).

Description

An object of class "Anno" that contains associations between Gene Ontology Cellular Component terms and Rfam RNA families. This data is prepared based on the Rfam database (see http://rfam.xfam.org) and http://geneontology.org/external2go/rfam2go.

Usage

1

Value

an object of class Anno. It has slots for "annoData", "termData" and "domainData":

  • annoData: a sparse matrix of RNAs X terms

  • termData: variables describing ontology terms (i.e. columns in annoData), including: "ID" (i.e. term ID), "Name" (i.e. term Names), "Namespace" (i.e. term Namespace), and "Distance" (i.e. term Distance to the ontology root)

  • domainData: variables describing RNAs (i.e. rows in annoData), including: "id" for Rfam accession ID, and "level" always equals "Rfam", "description" for Rfam description
