I'm observing the same phenomenon. I'm using R.app GUI 1.53 (6335) x86_64-apple-darwin9.8.0 on 10.7.5.

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():

<br>Any ideas? Thanks, Earl Brown
