Data Desk is an interactive data analysis package that helps you find patterns and relationships in your data. This package contains several items to help you learn and use Data Desk.
1) The “Getting Started Using Data Desk” file offers a quick overview of Data Desk.
2) The “Advanced Data Desk Features” file provides an introduction to Data Desk using an analysis of real data.
3) The Help file offers on-line help.
4) A list of Frequently Asked Questions on our web site at www.datadesk.com provides detailed answers for many popular questions.
Those of you who have used previous versions of Data Desk will find that the interface has not changed much. Even if you used to use Data Desk on Macintosh and are now running it on Windows, you should feel right at home with the interface.

NEW FEATURES
Parallel Coordinate Plots:
Parallel Coordinate plots are used to explore multivariate data. It displays variables side by side with lines connecting each point. To create a parallel coordinate plot in Data Desk, select the desired variables and choose the Dotplot Side by Side command from the Plot menu. Click on the plot’s title bar and choose the Lines > Show Lines command from the Modify menu.
The variables selected need to be from the same relation. Also, it is helpful if the variables are measured on the same scale. If they are not it might be wise to standardize the variables before plotting them.
Library Picture Format
Pictures may be place in a separate file (located in the Library folder) to be referenced and opened by corkboards in the file that is currently opened.
II. The Public Interchange Format
Data Desk 6.3 can read a write a new public interchange file format called SHOE. SHOE files will be supported by all future versions of Data Desk so version 6.3 will be able to read files created by version 8.
SHOE is a public format so that any program can write a file which can be read by Data Desk. The specifications for these files are posted on our web site. SHOE files are much smaller than standard files so they can be used to archive or transfer large files. SHOE files can also be used for transferring extremely large datafiles to Data Desk.
On windows SHOE files have a “.sho” extension. On Mac, SHOE files have a icon that is only slightly different than the standard Data Desk icon. Double-clicking on these files will launch Data Desk.
To create a SHOE file, choose the Clean Datafile… command from the File menu and click the Save SHOE Copy button.
III. New Derived Variable Functions
Note: the SHOE public interchange file format supports only zero-based derived variable functions. Derived variable expressions using one-based functions that are in files saved in the SHOE format are reexpressed using equivalent zero based functions.
