I don't think one session can get information from another session, except use load.
I simulate you situation within one session. Hope it helps. #Simulate the first session object1 <- 1:10 save(object1,file="ob1") rm(object1) object1 #Simulate the second session object2 <- (1:10)*2 save(object2,file="ob2") rm(object2) object2 #Simulate the third session load(file="ob1") load(file="ob2") object1 object2 ----- A R learner. -- View this message in context: http://r.789695.n4.nabble.com/multiple-R-sessions-from-one-working-directory-using-GNU-screen-tp2312037p2312461.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
