som_modify_dataset

sD = som_modify_dataset(sD,action,varargin)

SOM_MODIFY_DATASET Add or remove components or samples to/from a data struct.

 sD = som_modify_dataset(sD, 'addcomp', D, [indsto], [cnames})
 sD = som_modify_dataset(sD, 'addsamp', D, [indsto], ['norm'])
 sD = som_modify_dataset(sD, 'removecomp', [inds])
 sD = som_modify_dataset(sD, 'removesamp', inds)
 sD = som_modify_dataset(sD, 'extractcomp', [inds])
 sD = som_modify_dataset(sD, 'extractsamp', inds)
 sD = som_modify_dataset(sD, 'movecomp', inds, indsto)
 sD = som_modify_dataset(sD, 'movesamp', inds, indsto)

  Input and output arguments ([]'s are optional)
   sD      (struct) data struct
   action  (string) 'addcomp', 'addsamp', 'removecomp', 'removesamp', 
                    'extractcomp', 'extractsamp', 'movecomp', or 'movesamp' 

   other input arguments depend on the action

   'addcomp': 
   D        (matrix) data matrix, size [dlen x d]
            (struct) data struct, size of .data field [dlen x d]
   [indsto] (vector) new indeces of the components, length=d
   [cnames] (cellstr) of size d x 1, the component names

   'addsamp': 
   D        (matrix) data matrix, size [n x dim] 
   [indsto] (vector) new indeces of the samples, length=n
   ['norm'] (string) specified if the normalization procedure
                     should be applied to the new samples

   'removecomp', 'extractcomp': 
   [inds]   (vector) indeces of the components to be removed/extracted. 
                     If not given, a prompt will appear from which the
                     user can select the appropriate components.

   'removesamp', 'extractsamp': 
   inds     (vector) indeces of the samples to be removed/extracted

   'movecomp', 'movesamp': 
   inds     (vector) indeces of the components/samples to be moved
   indsto   (vector) new indeces of the components/samples
