Asunto: Bug in R.app 1.53 - Phantom Text


Just to chime in that there is a "phantom text" thread running with this issue - there are a few people experiencing this. 


I have been trying to isolate the problem, unsuccessfully, but it looks like assignment operators (<- or =) in a script, trigger this. It looks like whatever mechanism in the console keeps an eye on the script is grabbing things and inserting them before the prompt. 


I also wonder if it is only happening to people on Mountain Lion? 



Can someone suggest a way to get a "status shot" from the OS for R when this happens so we can help more?

When I run code in R.app, in addition to getting the results I expect, the console also randomly prints out previously submitted code and places it before the prompt arrow and/or before the output of what my code asks R to do. 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():

Any ideas? Thanks, Earl Brown
