An off-list email ... Allen is not really set on the global environment stuff, but just want to control the name of the variable the return value of the function is assigned to. Let us say we have the following name_variable = "my_name" my_function = function() { 3 } Then you do assign(name_variable, my_function()) This will create a variable called my_name which will have a value of 3. In other words, when you want to control the name of the variable which holds the result of the function, you do it all outside the function, not as you were suggesting, which were roughly to have something like my_function = function(name_variable) { 3 MORE CODE } and then have my_function("my_name") create a variable with name "my_name" and value 3.
