Example: Input from Active Dataset (CLUSTER command)

GET FILE='data/crime.sav.
PROXIMITIES MURDER TO MOTOR
  /VIEW=VARIABLE
  /MEASURE=PH2
  /MATRIX=OUT(*).
CLUSTER
  /MATRIX=IN(*).

• PROXIMITIES uses the data from crime.sav, which is now the active dataset. The VIEW subcommand specifies computation of proximity values between variables. The MATRIX subcommand writes the matrix to the active dataset.
• MATRIX=IN(*) on the CLUSTER command reads the matrix materials from the active dataset. Since the matrix contains distances between variables, CLUSTER clusters variables based on distance measures in the input. The variable list is omitted on the CLUSTER command, so all variables are used in the analysis. The slash preceding the MATRIX subcommand is required because there is an implied variable list. Without the slash, CLUSTER would attempt to interpret MATRIX as a variable name rather than a subcommand name.
