...: rapply(list(test), eval, envir = fenv) I thought I explained in the question that the above code does not work. It does not throw an error, but the behavior is no different (at least in the output or result). Using the above code still results in the x object not being stored in fenv on 3.1.2.

...er stored in "fenv," but it is when I run the same code on 3.2.1. However, the given example stores "x" in "fenv" on 3.1.2, but throws the error I gave when run on 3.2.1.

Bill, Is your conclusion to just update the code and enforce using the most recent version of R?

....2.1 the code throws an error: Error in eval(substitute(expr), envir, enclos) : object 'X' not found I could not find anything in the release notes that would explain this change. Changing evalq to eval works in 3.2.1, but eval does not store x in the given environment in 3.1.2. Thanks, Dayne [[alternative HTML version deleted]]

..., envir, enclos) : object 'X' not found lapply(list(quote(1+myNumber)), eval, envir=list2env(list(myNumber=17))) #[[1]] #[1] 18 Make the FUN argument function(arg)sys.call() to see some details of the change.

I am curious why you used evalq instead of eval in this code.
