You can set what categories and data are included in tables and analyses via the Missing Data settings in the Value Attributes of a Variable Set, see Variable Sets. However, sometimes you do want to show a category on a table that may be missing data for some of the cells in your table. In Displayr, missing values in built-in tables is shown by NaN, but you are able to change the NaN to something else if needed. This article describes how to apply a rule to go from a table showing missing values as NaN...
...to a table where the NaN has been replaced with specified text (e.g. - ):
Method
1. Select your table.
2. Go to Data > RULES on the object inspector.
3. To apply the rule, select the Plus (+) > Modify Cell Content > Change Missing Data (NaN) Symbol.
4. Enter the text to replace the missing data (NaN).
5. Press OK.
