Edit variables list
Allows to edit the variables list.
MedCalc automatically keeps track of variables that you add in the spreadsheet, while you enter data, or when you import data from other files. When you save the data, the variables list is included in the file.
However, from time to time an error may occur in the list (e.g. double occurrence of a variable, or non-existing or deleted variables), and with the command Edit variables list you can edit the list.
The variables list is displayed in the left side box in the dialog box.
When you click the Create list button, a new list will be created based on the column headers in the spreadsheet.
Click New when you want to create a new derived variable. In the Variable properties dialog box you can enter the formula for the derived variable, and optionally enter a descriptive label for the variable and assign labels to data values.
When a variable is selected in the left box, you can click the Properties button to edit the variable properties.
You can select one or more variables in the list and next click the Remove button to remove the selected variables from the list. This will just remove the variable name from the list, the corresponding columns in the spreadsheet will not be deleted.
When you click the Clear list button, the entire list will be cleared.
