Creating a data field as a number series

 

serie	Create a series of numbers
-d <data>	existing data
-fout <field-name>	field to be generated
[-start <start-value>]	minimum value for series (or 0)
[-step <step-value>]	step between the values (or 1)

This command creates a new data field by generating numeric values. The values are created by starting from the <start-value>, and by increasing the generated value by <step-value> each time. The <step-value> can be zero or negative, too.

Example: The following example demonstrates how identifiers can be generated for data records.

NDA> load boston.dat
NDA> serie -d boston -fout boston.id -start 0 -step 1
NDA> getdata boston.id
1                           # Type = 1 (integer)
0                           # The created series
