[BioC] GraphNEL object retrieve edgenumber from acc() or is it list of lists?

[schaefe9 at informatik.uni-bonn.de]

Hello everyone,

Im working with graphNEL object and want to extract all the nodes which
have adjacent nodes with at least 20 nodes in between them.

acc(graph, graphnodes) obviously provides a list for the accessable
nodes of every node from a node and a number of the edges between them.
Like this:

$`hsa:8379`
hsa:100131844     hsa:10393    hsa:246184     hsa:29882     hsa:29945
            1             1             1             1             1
    hsa:51433     hsa:51434     hsa:51529     hsa:64682      hsa:8697
            1             1             1             1             1

$`hsa:51343`
hsa:23594 hsa:23595  hsa:5001  hsa:5000  hsa:4999  hsa:4998
        8         8         8         8         8         8

and so on. However I want know access the numbers so that I can compare these
edgenumbers and only retrieve the nodes with an accessable node with at least
20 edges as mentioned above. How can I achieve this? In addtion whats the
data
type of the result of acc(). Is it a list in a list?

Thank you
