_D_e_s_c_r_i_p_t_i_o_n:

     Detect clusters in a hierarchical dendrogram using a variable cut
     height approach. Uses only the information in the dendrogram
     itself is used (which may give incorrect assignment for outlying
     objects).

_U_s_a_g_e:

     cutreeDynamicTree(dendro, maxTreeHeight = 1, deepSplit = TRUE, minModuleSize = 50)

_A_r_g_u_m_e_n_t_s:

  dendro: Hierarchical clustering dendrogram such produced by 'hclust'.

maxTreeHeight: Maximum joining height of objects to be considered part
          of clusters.

deepSplit: If 'TRUE', method will favor sensitivity and produce more
          smaller clusters. When 'FALSE', there will be fewer bigger
          clusters.

minModuleSize: Minimum module size. Branches containing fewer than
          'minModuleSize' objects will be left unlabeled.

_D_e_t_a_i_l_s:

     A variable height branch pruning technique for dendrograms
     produced by hierarchical clustering. Initially, branches are cut
     off at the height 'maxTreeHeight'; the resulting clusters are then
     examined for substructure and if subclusters are detected, they
     are assigned separate labels. Subclusters are detected by
     structure and are required to have a minimum of 'minModuleSize'
     objects on them to be assigned a separate label. A rough degree of
     control over what it means to be a subcluster is implemented by
     the parameter 'deepSplit'.

_V_a_l_u_e:

     A vector of numerical labels giving assignment of objects to
     modules. Unassigned objects are labeled 0, the largest module has
     label 1, next largest 2 etc.
