Without boring into it, doesn't it seem likely that one behavior is related to "set messages" and the other to "set error messages"? Try setting one on and the other off and see if the behavior is relative.

Subject: [RBASE-L] - How does R:Base choose how to display error messages?


I notice that when I'm running a program from the R> prompt with ERROR MESSAGE set to ON, there are two different types of behavior:

1. R:Base displays a popup error message with an OK button. When you click OK, the error message also appears on the output console and R:Base continues processing.

2. R:Base skips the popup, displays the error message on the console, and continues processing.

I have a process in which I want to force the second behavior (because I'm really trying to create a text file full of the error messages without having to hit OK for each one).

The problem is, I have no idea when R:Base uses one behavior and when the other.

Does anyone have any insight?
