[R-SIG-Mac] History problems with R.app GUI 1.20

[Rob J Goedman]

Vili,

What are your preference settings for history (Startup preferences)  
under R.app?
By selecting the 'cleanup history entries' the extra lines should  
disappear.

R.app history is kind of a superset R history in that it does handle  
multiple line
history, but unfortunately that means you cannot easily go back from  
R.app
to R (the other way should be no problem).

Regards,
Rob
