Hi, I have a binary matrix and I would like from it make a cluster by agglomerative method (like agnes), and then generate a ascii art dendrogram. See the illustration: binary matrix ascii art dendrogram ABCDEFGH P1 0101011101 +---------P1 P2 1000101001 => (Agnes) => +------| P3 1001011101 | +---------P3 P4 0101101110 +------| | +------------------P2 | +--------------------------P4 Someone could help-me???
