hi,
i have come across the following problem with the graph::edgeMatrix()
function when the input object is a 'graphBAM' object:
library(graph)
g <- graphBAM(data.frame(from="1", to="2", weight=1))
edgeMatrix(g, duplicates=FALSE)
[,1]
from 1
to 2
edgeMatrix(g, duplicates=TRUE) ## here is the problem !!
[,1]
from 1
to 2
edgeMatrix(as(g, "graphNEL"), duplicates=TRUE) ## but here works !!
[,1] [,2]
from 1 2
to 2 1
note that when coercing 'g' to a 'graphNEL' object, then it works as
expected.
thanks!!
robert.
