[R-SIG-Mac] stdout Phantom Text

[Simon Urbanek]

AFAICS this happens if you don't have anything defined in the editor window and start typing something like

a<
or
a== 

where "a" can be any identifier. It goes away the moment you have a function defined in the document.

Note that you can disable this by setting "Redirect stdout/err" to NO at the cost of no longer seeing any stdout/err in the console.

Unfortunately this is really hard to trace, because it is output that is somehow generated on stdout and then fed back to R, so tracing the output doesn't give you the source. My best attempt how to trace it is really going back in the GUI revisions to see where it started which is what I plan to do next (once I have a quiet minute) ...

Cheers,
Simon

Its quite an irritating little thing that I am sure has something to do with other programmes on my machine (I am using PERL, GNU parallel and various other unix software for genomics work (like samtools and requirements, etc). Short of deleting all of that stuff, I wonder if there is a way to see the activity.....
