First let's read in our data which sits in an Excel spreadsheet called DEFAULT.XLS. We click on the File Menu, select [Open] and see a display like the one below.
Note that CART will recognize a broad range of file formats, a few of which are visible in the selector box. Altogether there are about 85 formats to choose from including all the major databases, statistical packages, and spreadsheets. ODBC connectivity is also supported as is plain ASCII.
Since our data was provided to us as an Office 2000 document we select the [Excel 97/2000] format and then click on our data file.
