[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
