Class For Constrained Hiereachical Clustering
Description
Files belonging to this class hold information about the constrained agglomerative clustering and allows one to display results graphically.
Format
A file belonging to this class is a list with elements:
- merge
A (n-1) by 2 matrix. Row i of file
"merge"describes the merging of clusters at step i of the clustering. If an element j in the row is negative, it means that observation -j was merged at this stage. If j is positive, it means that the merge was with the cluster formed at the (earlier) stage j of the algorithm. Thus negative entries in file"merge"indicate agglomerations of singletons, and positive entries indicate agglomerations of non-singletons.- height
A set of (n-1) non-decreasing real values. The clustering height is the value of the criterion associated with the clustering method for the particular agglomeration.
- order
A vector giving the permutation of the original observations suitable for plotting, in the sense that a cluster plot using this ordering and matrix merge will not have crossing branches.
- labels
Labels for the clustered objects.
- method
The agglomerative clustering method that has been used.
- call
The call that produced the result.
- dist.method
The distance that has been used to create dissimilarity matrix
"d"(only returned if the dissimilarity matrix object has a "method" attribute attached to it).- links
A copy of the list of edges (if a matrix of edges was provided to the function).
- coords
A copy of the coordinates (if coordinates were provided to the function).
Details
The class inherits from hclust-class and describes the
tree produced by the constrained clustering procedure.
All class members except links and coords are identical to
those in hclust-class. several methods designed to process
these objects are expected to also work with constr.hclust-class
objects.
Value
No return value
