medoidPath(data, cl, reorder = FALSE)
centroidPath(data, cl, reorder = FALSE)A dataframe
Path length, defaults to 10
If TRUE uses DendSer to reorder the path dser
A vector of variable names. The returned tour is for this subset of variables.
ignored
(pamPath only) For datasets with more than maxn rows, use maxn randomly selected rows.
A vector specifying cluster membership for rows of data.
A dataframe with the path
kmeansPath(): Constructs a tour of data space following length k-means centroids
pamPath(): Constructs a tour of data space following length pam medoids
claraPath(): Constructs a tour of data space following length clara medoids
medoidPath(): Returns a path visiting cluster medoids
centroidPath(): Returns a path visiting cluster centroids
