vec2distm {gclus} | R Documentation |
vec2distm
converts a vector to a distance matrix.
vec2dist
converts a vector to a dist
structure.
lower2upper.tri.inds
is the same as lower.to.upper.tri.inds
from package cluster. It computes an index vector for extracting or reordering a lower
triangular matrix that is stored as a contiguous vectors.
diag.off
returns a vector of off-diagonal elements of a matrix.
off
specifies the distance above the main (0) diagonal.
clus2memship
converts a list whose ith element contains the indices
of objects in the ith cluster into a vector whose ith
element gives the cluster number of the ith object.
memship2clus
converts a vector whose ith
element gives the cluster number of the ith object into a list
whose ith element contains the indices
of objects in the ith cluster.
