Editing Data and Tables
The following sections describe how to edit data that is in a table, including editing cells themselves
and making changes to rows and columns.
Editing Cells
To edit the contents of a cell:
1 Click a cell that already has a value. It is highlighted, as shown in Figure 3.31
Figure 3.31 Editing the Contents of a Cell
2 Click it a second time. The cursor becomes a flashing text insertion bar.
3 Edit its value.
Editing Column Names
There are many ways to edit a column name. Choose a way from the list below:
• Select the column and begin typing.
• Select the column, and then click the column name and edit.
• Double-click or right-click the empty area around the column name and select Column Info. Edit
the name in the Column Info window that appears.
• Double-click the column name in the column panel and begin typing.
Recoding Data
If you have data that is coded incorrectly (for example, contains typos or incorrect wording), you can
quickly recode it so it follows a consistent format. You can also use recode to replace missing or empty
values.
JMP displays a window that contains selected columns’ unique values and enables you to enter new
values to replace them:
1 Highlight the column(s) that contain data you would like to recode.
2 Select Cols > Recode. The Recode window appears (Figure 3.32). In this window, the Count
column lists the number of occurrences each value has in the data table.
