In belasi01/Cops: C-OPS Processing

This function will create a tcl/tk dialog box to get user input. It has been written to be extensible so the R programmer can easily create a dialog with any number of varaibles with custom labels and data conversion of the user entered data. The function will return a list where the element names are vars and the value is the user input. By default, all entry will be converted using the as.character function. However, this can easily be altered using the fun parameter. For example, if integers are required, use fun=c(as.integer, ...). It is also possible to write custom functions that can serve as a data validation. See the examples.
