CalcMerge | R Documentation |
This is the auxiliary function of the package. It generates the binary vector to mark the nodes with identical class labels.
CalcMerge(hc,node,class)
hc |
An object of class hclust which describes the tree produced by the clustering process.There are such components: merge, height, order, labels,call,method,dist.method. |
node |
a list of lists of length n-1 |
class |
a vector of length n, which stores the class labels of the dataset objects. |
This is the auxiliary function of the package. It generates the binary vector to mark the nodes with identical class labels. The node or subtree with the elements, having the same class labela are marked by value 1, otherwise 0. The output vector is used as input to function SubTree
, which simplifies the hierarchical tree in order to increase the efficiency of the dynamic programming algorithm.
flag |
a binory vector of length n-1. |
