[R] I need to compare ranking (1-15) across 10 replicates to see if the ranking changes significantly- how???

Hi there
all suggestions much appreciated! so our investigation is looking into the
time pairs of guppies spend interacting... we have raw data in minutes, but
have ranked each possible association between pairs (out of 15 possible) in
order of frequency of occurence during a 20 min recording period. then rinse
and repeat 10 times... :-D
so this is what we have: (rows are replicates, columns different
interactions)
L/L L/S L/B L/D L/LT S/S S/B S/D S/LT B/B B/D B/LT D/D D/LT LT/LT
1 12 10 3 1 8 11 6 5 15 14 7 4 8 2 12
2 4 2 1 3 5 15 13 6 12 11 14 6 8 10 9
3 12 14 8 6 2 15 12 4 5 7 10 1 11 8 3
4 7 11 1 10 4 6 5 8 12 14 13 2 9 14 3
5 4 10 2 10 12 8 7 3 6 12 14 1 14 9 5
6 2 8 9 5 13 11 12 7 6 1 15 4 13 3 10
7 3 4 6 13 11 8 2 14 12 1 14 9 10 5 7
8 2 9 3 5 1 5 4 10 15 11 13 12 7 7 14
9 5 6 1 9 11 13 4 10 3 8 13 2 15 7 12
10 3 11 9 15 7 10 6 4 8 1 13 2 12 4 14
Score 54 85 43 77 74 102 71 71 94 80 126 43 107 69 89
Ranking 3 10 1 8 7 13 5 5 12 9 15 1 14 4 11
is it possible to run an ANOVA on this, to assess the stability of
interactions? With the idea that if the ranking changes a significant amount
between replicates, associations are not being maintained...??
all help and advice gratefully received!
Thanks
