[R] transition matrices

I am working with transition matrices of sequences of animal 
behaviours.  What I would like to do is parse the original matrices, 
adjusting row/column order so that the matrix has its main values in blocks 
surrounding the diagonal.  This would cause behaviours involved in 
functional groupings (e.g. grooming, resting, foraging etc) to appear as 
This can be done manually by applying subjective 'prior knowledge' of 
sequences, however I would like to have an algorithmic/objective method to 
generate at least a first cut ...
Any suggestions or hints (even just thoughts) would be much appreciated,
