Title | How to avoid outputting the variable twice | |
Author | Chinh Nguyen, StataCorp |
Stata 10 now uses the Data Browser control for the Variables window. This is the same control the Finder uses for displaying files in in list form in a folder window. The Data Browser behaves differently depending on where you click in the control.
To explain this, let’s look at two scenarios.
The Data Browser controls also allow keyboard navigation of the list in the control. Thus you can use keyboard navigation once the focus is set to the Variables window. A few of the keyboard navigations are as follows:
The reason a variable may show up twice after pressing Return is because you clicked a blank area of a cell containing a variable name and then pressed Return. This sequence outputs the variable name into the Command window, sets the keyboard focus to the Variables window, and enters the variable name again once Return is pressed.
To avoid this behavior, you must click a variable name in the Variables window, not a blank area.
