List of data frames or matrices representing b=1,...,B data blocks of dimensions n x p_b.
which2pair
Integer vector of size 2 (or NULL)
Value
List. Same length as datablocks when which2pair = NULL, or augmented with one paired data block.
Details
Only use this function when you wish to pair two data blocks. If which2pair = NULL the output
matches the input. If not, the function adds a paired data block, pairing the two data blocks corresponding to the elements of
which2pair.
