Duplicates a leaf in a tree. Useful for non-parametric bootstraping trees since it emulates what would have happened if the tree was constructed based on a row-sample with replacments from the original data matrix.

logical (TRUE). Fix the midpoint value. If TRUE, it overrides "fix_members" and turns it into TRUE (since it must have a correct number of members in order to work). values using rank_order.dendrogram
