If you don't have control of E to make the changes Gabor suggested, then I don't think you can do it without iteration. But you can leave V alone as follows: V2 <- new.env(parent=V) eval(E, envir=V2) # Assignments happen in V2 Now iterate over V2 to move things into .GlobalEnv if you want, e.g. names <- ls(V2, all=TRUE) for (n in names) assign(n, get(n, envir=V2)) Duncan Murdoch __ 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.
Re: [R] eval using a environment X but resultsin .GlobalEnv
Try this: .GlobalEnv$x <- 3 Also x <<- 3 will work if there is no x between V and the global environment but if there is then that one will get set rather than the one in the global environment.

[R] eval using a environment X but resultsin .GlobalEnv
Hello, Suppose I have an expression, E, which accesses some variables present in an environment V. I do this via eval(E,envir=V) however all assignments end up in V. I would like the results of assignments in E to end up in the .GlobalEnv ? Or at least the calling environment. Is there a quick way to this instead of iterating over all objects E and assigning into .GlobalEnv?
