Given a symmetric rank/graph matrix \(R\), compute the within-group
rank sums for the two samples.
Usage
r.stat(R, sample1ID, sample2ID)
Value
Numeric vector c(Ux, Uy).
Arguments
- R
Symmetric nonnegative matrix (N x N) with zero diagonal.
- sample1ID
Indices for group X.
- sample2ID
Indices for group Y.
