MissingDataGUI: The Starting of Missing Data GUI.

In MissingDataGUI: A GUI for Missing Data Exploration

Description

This function starts an open-files GUI, allowing 1) selecting one or more data files; 2)opening the main missing-data GUI for one data file. The missing data GUI consists of two tabs. In the summary tab, there are a list of all variables, a list of variables having missing values to color by, two radios for imputation methods and graph types respectively, a checkbox group for the conditional variables, four buttons and a graphics device. In the help tab, the layout is the same as the summary tab. But when the users move their mouse on those widgets, or click any of those radios or buttons, the functions of all widgets will be described at the place of the graphics device. The attributes of the variables can be changed. If the user double clicks on any variables in the top left table of missing-data GUI, an attribute window will pop up. Then the name could be edited, and the class could be changed to one of the four classes: integer, numeric, factor, and character. When a numeric variable is changed to a categorical variable, the condtions in the bottom left checkbox group will be updated. If the list of the color by variables is very long, the selector allows text entry to find the variable when this widget is active.
