I am looking for data at the level of each triad. 

E.g.

I have two transitive triads in a network A->B->C<-A and E->F->G<-E

Ideally, I want something that shows:

Triad

in-2-star

out-2-star

2-path

1

C

A

B

2

G

E

F

If anyone has code that identifies nodal position for each triad, it would be super helpful! 

Thanks!

Positions within fragments are returned as an additional result

Positions which are interesting for us should be marked in fragment with the label "1".

Therefore fragments for the three positions you mentioned should be defined as:

Fragment for counting position "2-in-star":

*Vertices 3
1 "a" 
2 "b"
3 "1"
*Arcs
1 2
1 3
2 3

Fragment for counting position "2-out-star":

*Vertices 3
1 "1" 
2 "b"
3 "c"
*Arcs
1 2
1 3
2 3

Fragment for counting position "the 2-path":

*Vertices 3
1 "a" 
2 "1"
3 "c"
*Arcs
1 2
1 3
2 3

Number of times each vertex is in a specified position within a fragment
is then returned as an additional vector called [Marking].

Subject: [SOCNET] List of ordered transitive triads

Hello All,

I have a simple task but I cannot seem to find a solution for some reason. I need to generate a list of transitive triads in a given network. I also want the list to indicate node position within the triad. That is, for each triad I want to be able to identify which node is the 2-in-star, the 2-out-star, and the 2-path. Pajek generates a list within hierarchy via the ‘locate fragment’ algorithm but I don’t believe it orders the nodes by position. Does anyone know if UCINET does this? Or is there a code in an R package that can be readily used? 

Thanks for your help in advance!
