Your are correct, in that ?Syntax does say that operators with equal precedence are given precedence from right to left

However, I am having trouble seeing how it would be possible to return different results from:

```
! export %in% c("none", "any", "namespace")
``` 
vs
```
!( export %in% c("none", "any", "namespace"))
``` 
although, I can see that the second is preferable because it more clearly represents the intention.
(but please let me know if I am wrong ... I have made this error many times)
