SPSS 16 introduced Extension commands. These are user-defined syntax
that is implemented in Python or R programs. That allows you to use
the programs without knowing Python or R. Once installed, they are
automatically available in SPSS.
Here is a list of the extension commands currently available for
download from SPSS Developer Central (
www.spss.com/devcentral). These
all require at least SPSS
16.0.2 and the Python Programmability Plug-
In.
For most of these, executing
command-name /HELP.
provides a full description of the syntax.
These are generally structured so that the underlying implementation
can be called directly as a Python function if you want to use them in
a BEGIN PROGRAM block, and some have extra functionality available
when used this way.
HIDECOLS and SCRIPTEX are brand new.
