Regarding the issue of "inserting a newline during debugging":
If I remember correctly, this issue didn't happen in older versions of R.
and it seems connected to some other issues.
There generally seems to be something different with how the R Console is
being rendered, and it doesn't seem to be quite as stable. I'm speaking of
the difference between versions 2.8 (approximately) to 2.11 or 2.12, on
Windows machines with XP and 7.
One piece of evidence is the other issue where the cursor disappears when
running commands, and actually appears somewhere else that doesn't make
sense. (This has been discussed already in R-Help)
However, I have also noticed weird behavior when
- working remotely
- using Eclipse with the StatET plug-in for R
- when using Tcl\Tk GUI windows
In general, I have been experiencing more instability with the GUI. It
seems to have more lag or something.
I have also had some system freezes which I think were related to R. Since
it always happens after I've been remoting into my desktop, and then come
back to work and view the R console.
Sorry this is a little off topic, I just had the newline insertion thing
happen to me (since I wasn't using Eclipse), and I thought I would check
back to see if there was a way to turn it off.
Thanks,
Gene
