\name{DOOFFSPRING} \alias{DOOFFSPRING} \title{Annotation of DO Identifiers to their Offspring} \description{ This data set describes associations between DO terms and their offspring terms, based on the directed acyclic graph (DAG) defined by the Disease Ontology Consortium. The format is an R object mapping the DO terms to all offspring terms, where an ancestor term is a more specific DO term that is preceded by the given DO term in the DAG (in other words, the children and all their children, etc.). } \details{ Each DO term is mapped to a vector of offspring DO terms. Mappings were based on data provided by: Disease Ontology With a date stamp from the source of: 20100823 (sub_version 1689) } \references{ \url{http://do-wiki.nubic.northwestern.edu/index.php/Main_Page} %and \url{http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene} } \examples{ # Convert the object to a list xx <- as.list(DOOFFSPRING) # Remove DO IDs that do not have any offspring xx <- xx[!is.na(xx)] if(length(xx) > 0){ # Get the offspring DO identifiers for the first two elents of xx doidentifiers <- xx[1:2] } } \keyword{datasets}
