Reform M-values into a two-column matrix.
Reform M-values into a matrix with two columns representing matched control and case groups. It concatenate M-values pair-by-pair based on the design matrix.
The input M-values matrix, NA is not allowed.
A design matrix, which can be generated by 'stats::model.matrix'. If the M-values are totally paired or single paired, just leave it to be NULL.
A matrix with two columns representing matched control and case groups. If a sample has no paired sample in another group (say group B), then the values in group B will be represented by NA.
