Hello everyone,
How would I randomly select 100 nodes to look at out of these approx.
25,0000? I'm practicing constructing a citation network.
edgeList below is an edge list.
> head (edgeList)
to from
[1,] "4US6" "3US320"
[2,] "4US6" "4US1"
[3,] "6US280" "1US393"
[4,] "6US280" "1US53"
[5,] "6US280" "3US133"
[6,] "14US179" "5US321"
> G <- graph.edgelist(edgeList, directed=FALSE)
> G
IGRAPH a473ce7 UN-- 25417 216738 --

[22] 15US396--6US358 15US396--7US73 16US1 --11US603
+ ... omitted several edges
Can I use the sample () function? I'm working with the text Humanities
Data in R (Arnold & Tilton). I'm working within the igraph library.
