[BioC] Kmeans help

[sidahmed BENABDERRAHMANE]

Dear all,
Let me ask my question on this list because I am a new user of R.
I have a problem with the Kmeans clustering method . In fact, having a 
symmetric matrix:


         g1      g2      .. ...       gn
g1     1        0,3                   0,6
g2      0,3      1                    0,4
.         ......................................
.         ....................................
..     ...........................................
gn    0,6       0,4                       1

I should like to apply Kmeans on this matrix, knowing that there is no 
relation  R(object, attribute) but R(object, object) only.
Does the Kmeans algorithm works in this case?
Could you give me a syntax for testingKmeans on this matrix.

Thanks
