BTW, that %in% has precedence over arithmetic operations is surprising, error-prone, and doesn't cover any reasonable use case (who needs to multiply the logical vector returned by %in% by some value?) but that's another story:
The point here is that the %foo% operators all have the _same_ precedence. In principle, they can be user-coded, and there is no way to express what precedence is desirable. It may turn out slightly weird for %in%, but think of what would happen if %*% had lower precedence than addition.
