Except when using reference types, it should be safe to make the assumption that variables in R are passed as if by copy. In the interest of getting a quick workaround, does unserialize(serialize(L, NULL)) help? I would expect that to work unless your list contains something like environments. -- Best regards, Ivan ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
