So you are telling us in a *bug* report that R works as expected???
The current R Language Definition manual tells us in Section "Parser" - 
"Expressions" - "Infox and prefix operators" (which is 10.4.2 in the 
current version) the details on the order of precendence ("^" before 
unary "-"!).

Please read the docs before submitting bug reports!
