The clusters are relabelled to obtain a unique labeling.

relabel(object, by = "series", ...)

relabel(object, by, ...)An object of class "kccasimple" or
    "stepFlexclust".
If a character vector, it needs to be one of "mean",
    "median", "variable", "manual",
    "centers", "shadow", "symmshadow" or
    "series".
    If missing, "mean" or "series" is used depending on if
    object is of class "kccasimple" or
    "stepFlexclust".
    If an integer vector, it needs to indicate the new ordering.
Either an integer vector indiating the ordering or a vector of length one indicating the variable used for ordering.
Currently not used.
If by is a character vector with value "mean" or
  "median", the clusters are ordered by the mean or median values
  over all variables for each cluster. If by = "manual"
  which needs to be a vector indicating the ordering.  If
  by = "variable" which needs to be indicate the variable
  which is used to determine the ordering. If by is
  "centers", "shadow" or "symmshadow", cluster
  similarities are calculated using clusterSim and used to
  determine an ordering using seriate from package
  seriation.
If by = "series" the relabeling is performed over a series of
  clustering to minimize the misclassification.
