Chapter 9 Data Tables 239
Data Table Basics
On Macintosh, JMP relies on the Macintosh Type and Creator codes (if present) and secondarily on
three-letter filename extensions. (Type and Creator codes are invisible data that enable the Finder to display
a file with the correct icon corresponding to the application that created it; files with generic icons (such as
often appear on files obtained from other system) should have the filename extensions.
To import a specific worksheet in a Microsoft Excel file, specify the worksheet name in the Open command.
The following example imports the worksheet named small:
open("C:\data\cars.xlsx", Worksheets("small"));
Import multiple worksheets by including the worksheet names in brackets:
open("C:\data\cars.xlsx", Worksheets( {"small", "medium", "large"} ));
You can open data tables that are accessible through a Web page:
open("URL", )
The Web site URL is a quoted string that exactly describes the Internet location of a JMP data table. Add
the extension (for example, jmp) as an unquoted named argument if the URL for the data table does not
have the .jmp extension.
Note that the URL is case sensitive.
You can import data the same way. For example, specify text for a text import using your text import
preferences.
open("http://www.sas.com/", text);
If you do not add the text argument, the web page is returned as a string.
Additional formats include csv, script, and journal.
To import a password-protected file without entering the password each time, include the Password
argument:
Open Database
open(“housing.sas7bdat”, Password( "helloworld" );
Open Database opens a database using ODBC and extracts data into a JMP data table. See the “Extending
JMP” chapter on page 467.
Starting a New Data Table
You can start a new data table, or start a new data table and store its reference in a global. In either case, you
can specify a name for the table as an argument.
New Table();
dt=New Table("myName.jmp");
If you want to avoid a window appearing when you create a new data table, use the invisible keyword.
For example, to create an invisible table Abc with one column of ten rows,
dt=newTable("Abc", invisible, newColumn("X"),addRows(10));
