Hi Ed, I am not sure how this is non-obvious. You tried something and then didn't get the result you expected. In my mind, the next obvious step is to read the help page for get() to see what the API for that function is. And if you had done so, you would have seen: Description: Search by name for an object (?get?) or zero or more objects (?mget?). Usage: get(x, pos = -1, envir = as.environment(pos), mode = "any", inherits = TRUE) mget(x, envir = as.environment(-1), mode = "any", ifnotfound, inherits = FALSE) Arguments: x: For ?get?, an object name (given as a character string). For ?mget?, a character vector of object names.
