Answered 2019-Apr-03 at 16:56In this case the error message is confusing and it doesn't give a good hint about what is wrong.
The example that works specifies the aesthetic as aes(x = API)
. It is important that API
is unquoted. The example that doesn't work in effect specifies the aesthetic as aes(x = "API")
(not explicitly but that's what happens when you cycle through the loop).
So what it is necessary is to take "API"
and "unquote" it. You can achieve that with !!rlang::sym("API")
