Wondering if my next step is to implement the ranking algorithms in R?
Don't know exactly what you mean here. If you mean implement R's ranking
algorithms in java, that would be nice

measurement, in the same manner.

Please review and comment.
Thanks Again,

What exactly does column-wise mean. This just looks like Pearson's
R, which is already available in the SimpleRegression class. Do you
mean generation of correlation matrices?
Sorry, I should have been more specific. This will allow someone to
calculate the pearson r coefficient between
Sorry for the late link to code, and paper. Please note that this code
is not in a form that I would even think about commiting. I plan to
restructure all of the code and add unit tests, including all
algorithms. The best way to describe the current code is 'student
form', meaning there are file

it soon and see if it is helpful to other people.

I will send out a link to the pdf that describes KMotif, and the cross

. If anyone is interested we can continue this thread and I
will email my code, and purpose my new algorithms.
