Caution: When you try to delete thousands of rows, an alert might appear if your computer has insufficient memory to save data for undo. Either select fewer rows to delete or select Disable Undo from the Table panel red triangle menu. This option removes all actions from the undo history and does not record future actions. When the Disable Undo option is selected, it is in effect only while the data table is open; the setting is not saved with the data table.

A Missing Data Pattern Table shows the following patterns:
|
•
|
Row 1 shows that there are two instances where all rows in Trial 1, Trial 2, Trial 3, and Trial 4 have no missing values.
|
|
•
|
|
•
|
Row 3 shows that there are two rows in the source table whose missing values are in the Trial 3 and Trial 4 columns.
|
|
•
|
Row 4 shows that there is one row in the source table whose three missing values are in the Trial 2, Trial 3, and Trial 4 columns.
|
The Count column is assigned the frequency role. If you now use the Missing Data Pattern data table to run an analysis, JMP automatically uses Count as a frequency. For details, see Assign a Preselected Analysis Role in The Column Info Window.
