Extension Bundles from IBM SPSS
Extension bundles from IBM SPSS

This article provides a list of extension bundles that are authored by IBM SPSS and that are available for
download from the SPSS community (http://www.ibm.com/developerworks/spssdevcentral). Extension
bundles package custom components, such as custom dialogs and extension commands, so that they can
be easily installed. Most of the extension bundles listed here contain an extension command and an
accompanying dialog box that generates command syntax for the extension command in the same
manner as built-in dialogs. After an extension bundle is installed, the dialog box is accessible from the
IBM® SPSS® Statistics menus, and the extension command can be run in the same manner as any built-in
command such as DESCRIPTIVES.
The extension bundles listed in this article require the IBM SPSS Statistics - Integration Plug-in for Python
or the IBM SPSS Statistics - Integration Plug-in for R. Some extension bundles require both Plug-ins. For
information on installing Integration Plug-ins, see the topic "How to Get Integration Plug-ins" in the IBM
SPSS Statistics help system. The topic is located under Help>Core System>Frequently Asked Questions.
A number of the extension bundles listed here are installed with IBM SPSS Statistics - Essentials for
Python or IBM SPSS Statistics - Essentials for R and are noted as such in the description for the extension
bundle. Note that a newer version of one of these extension bundles might be available from the SPSS
community.
To install an extension bundle, you must have IBM SPSS Statistics 18 or higher.
v For users with IBM SPSS Statistics 18 - 21, you first download the extension bundle from the SPSS
community. You then install the extension bundle by choosing Utilities>Extension Bundles>Install
Extension Bundle from the SPSS Statistics menus and pointing to the location where you saved the
extension bundle.
v For users with IBM SPSS Statistics 22 or higher, you can install extension bundles from the Download
Extension Bundles dialog, accessible from Utilities>Extension Bundles>Download and Install
Extension Bundles within SPSS Statistics. You can also download the extension bundle from the SPSS
community and install the extension bundle by choosing Utilities>Extension Bundles>Install Local
Extension Bundle from the SPSS Statistics menus.
Note:
v The extension bundle installer attempts to download and install any R packages that are required by
the extension bundle and not found on your computer. For users of Windows Vista or later, you might
be required to run SPSS Statistics as administrator to successfully install required R packages. This
action is accomplished by right-clicking the icon for SPSS Statistics and selecting Run as administrator.
v If the extension bundle requires specific R packages and you do not have internet access, then you
must obtain the necessary packages from someone who does. Packages can be downloaded from and
then installed from within R. For details, see the R Installation and Administration guide, distributed
with R.
v The Download Extension Bundles dialog (requires version 22 or higher) also displays any updates that
are available for the extension bundles that are already installed.
v If you are installing extension bundles on SPSS Statistics Server, you can use a script to install multiple
extension bundles at once. For information, see Core System > Utilities > Extension bundles >
Installing local extension bundles > Batch installation of extension bundles in the Help system.

Help for each of the dialogs, included in the extension bundles listed here, is available by clicking Help
on the associated dialog box. The help is not, however, integrated with the SPSS Statistics Help system.
Complete syntax help for each of the extension commands included in the extension bundles listed here,
is available by running the command and including the /HELP subcommand. For example:
STATS TABLE CALC /HELP.
For version 23 or higher, the syntax help for a command is available by positioning the cursor within the
command (in a syntax window) and pressing the F1 key. In either case, the command syntax help is not
integrated with the SPSS Statistics Help system and is not included in the Command Syntax Reference.
Note: The F1 mechanism for displaying help is not supported in distributed mode.
To find the location, in the SPSS Statistics menus, of a dialog installed by an extension bundle, navigate to
Utilities>Extension Bundles>View Installed Extension Bundles and click the highlighted text for the
specific bundle in the Summary column on the Installed Extension Bundles dialog. The menu location is
provided on the associated Extension Bundle Details dialog.
Note: Extension bundles from non-IBM authors may also be available from the SPSS community.
