But the error message you show is not from the parser, and > parse(text="somePackage:::foo(x) <- value") expression(somePackage:::foo(x) <- value) attr(,"srcfile") <text> does work. The error you show arises is in the evaluator. That's because that is not legal code. :: and ::: are operators, not part of the language per se (although I have proposed changing that). The message comes at a check for a name, and base::length is not a name. It often helps to look error messages up in the sources. > For example: > > > x <- integer(4) > > base::length(x) <- 7 > Error in base::length(x) <- 7 : invalid function in complex assignment > > I've tried to put some back quotes on the left side of the assignment in > different ways but was not successful.
