[R-SIG-Mac] Bug in R.app 1.53

[Earl Brown]

(Potentially) helpful info about the bug:

I could NOT reproduce the bug when I opened my code file in TextWrangler and simply copied the code and then pasted it directly into the R console in R.app. The same thing happened when I used TextEdit and even MS Word. However, when I opened the code file with the built-in text editor in R.app and copied and pasted code into the R console I got the bug again. The same thing happened when I executed the code directly in the built-in text editor with the keyboard shortcut command + enter.

Could the bug be caused by the clipboard that the built-in text editor uses, which seems to be different than the system-wide clipboard that (I assume) TextWrangler, TextEdit and MS Word use. If not, why would the bug only be reproduced when I copy the code in the built-in text editor but not when I copy the code in other programs?

The grey color is output on stdout, typically it is a solicited output of system commands, for example try

> system("date")

The date will be in gray because the "date" command will print it out there so the GUI passes it on. It's not necessarily R.app itself generating that output.

Now the big question is who is creating that output - it can be anything from 3rd party hacks to R or custom top-level code used by the user. I don't see any printf/puts in the GUI code so it's unlikely produced by the GUI itself. I'll see if I can reproduce it ..

Cheers,
Simon

The color of this random, unwanted output is gray. This doesn't happen when I run my code in R in a Terminal window, nor did it happen before I upgraded to R 2.15.2 and R.app 1.53 a few days ago. Take a look at the two attached screen shots, one of R.app and the other of Terminal running the same code. And here's my sessionInfo():
