Hi All,
I recently upgraded to R 2.9.1 on my MacBook Pro running Mac OS X
10.5.7.
Previously, at the command prompt in the GUI the up arrow key
scrolled through the history. This still works for me, but every
time I scroll up the previous command gets an extra new line
character appended to it. I've attached a screen shot showing what
happens when I repeatedly use a single stroke of the up arrow to
recall the previous command. This is trivial, but makes using the
history rapidly more challenging because you have to delete though a
bunch of whitespace when trying to edit previously used commands.
This changed immediately after I upgraded to 2.9.1. Does anyone
know if something in R/GUI changed, or if I just had a setting that
I don't know about altered when I upgraded?
It seems that your preferences may have changed because the GUI didn't
change in 2.9.1 - make sure you have "Cleanup history entries" enabled
in Preferences->Startup->History.
Cheers,
Simon
