[R] Clearing Console- rm(list=ls(all=TRUE)) not working for me
Dear all again: I have been trying to clear weeks of codes in my R console, even after quitting and coming back another day!. One of you out there graciously suggested this rm(list=ls(all=TRUE)). I tried this but no dice. Codes tried. Ctrl +L , clears for the time... and the the latest i used ... rm(list=ls(all=TRUE)) Does anybody has another option of clearing the console of old codes?. Thanks, YA -- View this message in context: http://r.789695.n4.nabble.com/Clearing-Console-rm-list-ls-all-TRUE-not-working-for-me-tp3448681p3448681.html Sent from the R help mailing list archive at Nabble.com.

The person who gave you that advice really doesn't understand much if anything about R. He/she seems to have no idea about the distinction between completely distinct concepts. The rm(list=ls(all=TRUE)) command removes *objects* from your workspace. It has nothing whatever to do with your history of *commands* (``codes'' as you so quaintly put it). To get rid of past history you can simply edit your .Rhistory file and delete all but, say the last 50 lines. If you want to limit your history so that it never contains more than 50 lines you can do Sys.setenv(R_HISTSIZE=50) This has to be done every time a new R session is started. I have a similar command in my .Rprofile so that it gets done automatically. I use R_HISTSIZE=5000 however. I don't really understand why you object to having a fairly long history available to you. cheers, Rolf Turner
