DATA >PARTITION TO SETS


PURPOSE Transforms a partition indicator vector into a group by actor incidence matrix and display partition by groups.

DESCRIPTION A partition indicator vector has the form (k1,k2,...,ki...) where ki assigns vertex i to group ki.  So that (1 1 2 1 2) assigns vertices 1, 2 and 4 to block 1;  and 3 and 5 to block 2.  A group by vertex incidence matrix has vertices as its columns and the groups as the rows.  A 1 in row i column j indicates that actor j is a member of group i;  the values are zero otherwise.

PARAMETERS
Input dataset:
Partition indicator vector.  This can either be entered at the keyboard by specifying the elements of the vector, each number separated by a comma or space or as a UCINET dataset.
For partitions kept in a UCINET data file enter the filename followed by ROW (or COLUMN) and a number to specify which row or column of the file to use. Data type: Partition indicator vector.

Output dataset: (Default = 'PartitionToSets').
Name of file which will contain group by vertex incidence matrix.


LOG FILE A list of the groups.  Each group is numbered and specified by the vertices it contains.

TIMING O(N^2)

COMMENTS Partition indicator vectors enters using the keyboard are restricted to 255 characters.  Longer vectors should be specified using a UCINET dataset.
