[R] How to compare two square matrices

Hi, I have two matrices containing some probabilities score obtained from two different prediction programs. Now, I want to compare these two matrices to measure the difference. Could you please suggest some method to do this in R. Thanks Sabari [[alternative HTML version deleted]]

Re: [R] How to compare two square matrices

Dear Sabari, if you need a single number for comparison then there could be many options. You can calculate smallest absolute eigen value, or may be the determinant (i.e. a measure of volumn of matrices) or may be the smallest element in absolute term, depending on your research need. Thanks, --
