[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 blocks.
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,
