triad.census() gives you a vector of length 16. Each entry of the vector 
contains the number of occurrences for a triad of a given type. There are 16 
directed triads; the manual for the triad.census() function contains the 
description of each of them. For instance, the first entry in your case was 
113, which means that there are 113 occurrences of the empty triad in your 
graph (i.e. groups of three vertices A, B and C such that there are no edges 
between them).
