Chapter 9 Data Tables 235 Data Table Basics Data Table Basics JSL has full access to the values and properties of a data table. This section examines how to open and close data tables, view their properties, and interact with their data. Once you have a data table open, you accomplish most other data tasks by sending messages to a reference to the data table object. Objects acting on messages is a common theme in this book. As soon as you see how to create or open a data table object, step back and look at how objects and messages work. Getting a Data Table Object Any of the following methods of beginning to work with a data table produces a data table object. Opening a Data Table Opening a data table returns a reference to the data table. Usually, you assign the reference to a variable for later use. The usual argument for Open is a path (either relative or absolute) to the data table. For information about using POSIX filenames and the built-in path variables, see “Path Variables” on page 105 in the “Types of Data” chapter. Open("$SAMPLE_DATA/big class.jmp"); // just open the data table dt=Open("$SAMPLE_DATA/big class.jmp"); // open and assign a reference The path can be a literal path (absolute or relative) in quotation marks or an expression yielding a pathname. Relative paths are interpreted relative to the location of the .JSL file (if the script has been saved) or the JMP application (for an unsaved script); use ../ to move up one folder level. Example scripts typically use a relative path to open files from the installed Sample Data folder. You can also use the Set Current Directory command. If no arguments are given, Open presents a window prompting the user to navigate to a file. If a data table with that path is already open, then JMP does not read it again but instead brings that window in the front. If you have made changes, then the table is not the same as the one on disk that you might expect. Since JMP always keeps the whole table in memory, opening is equivalent to reading the whole file. Test for an Open Data Table In a script that depends on an opened data table, test to see whether the table is open using Is Empty() or Is Scriptable(). In the following example, the script performs a Bivariate analysis on Big Class.jmp and then closes the data table. Before proceeding to the Oneway analysis later in the script, If Scriptable() tests for the open data table. If 0 is returned, the table opens, and the script continues. dt = Open( "$SAMPLE_DATA/Big Class.jmp" ); obj = Bivariate( Y( :height ), X( :age ), Fit Line ); Close( dt ); ... If( Is Scriptable ( dt ), 0,
