You can do this:
fb <- function(bS, env = parent.frame()) { bS <- deparse(substitute(bS)) assign(bS, 3, env = env) } fb(bS) bS rm(bS) # or corresponding to your code fb(bS, env = .GlobalEnv) Of course when typed in both give the same result since the global environment is the parent frame. Please use <- and = consistently and properly space your source code.
