Hello, Im running R 1.8.1 on Win2000 and frequently using the function history() to keep track of what I did in my R session. In a recent session I typed history(max=Inf) and to my surprise there were only 15 lines of code where there should have been approx. 300 lines and I lost a lot of valuable work. Do you have any idea what caused this behaviour? help(history) didn't make me any smarter. Am I misunderstanding the concept of history()? I was expecting it to keep track of every command I type during my session.> R.version_ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 1 minor 8.1 year 2003 month 11 day 21 language R Any help is appreciated, Martin Keller-Ressel -- Erstellt mit M2, Operas revolution??rem E-Mail-Modul: http://www.opera.com/m2/

Note: It does not save the history, it does not set any limits. In order to save the history use savehistory(). A major part of the history buffer will be emptied if the buffer becomes full. You can set larger limits to the buffer by clicking "Edit" -> "GUI preferences" and set "buffer bytes" and "lines" appropriately.
