Arguments

g

A igraph object

org

A Go3AnnDbBimap object

Value

Simplified graph

Examples

library(igraph)
library(org.Dr.eg.db)
edges <- data.frame(
    ancestor = c("GO:0007154", "GO:0007267", "GO:0099536", "GO:0099537"),
    offspring = c("GO:0099536", "GO:0099536", "GO:0099537", "GO:0098916")
)
g <- graph_from_data_frame(edges)
g1 <- simplifyDAG(g, org.Dr.eg.db)
