Dear R gurus,
I am trying to create a nicer API interface for some R modules I have
written. Here, I heavily rely on S3 method dispatch mechanics and
makeActiveBinding() function
I have discovered that I apparently can't dispatch on function call
operator (). While .Primitive(() exists,

The details here are much more appropriate for R-devel, but please
check the help pages for ( and [, and note
- [ is generic and ( is not.
- the primitive `(` is used to implement constructions such as
(x - pi) and not x(...).
The special handling of operators such as [ is part of the parser,
Thank you both for very helpful answers. I have indeed missed the help pages
about ( and now the situation is more clear.
You can use this syntax by defining a function `x-` - function(...) {}
and it could be an S3 method, but it is a completely separate object from
x.
Unfortunately, it
How can I determine what S3 method will be called for a particular
first-argument class?
I was imagining something like functionDispatch('str','numeric') =
utils:::str.default , but I can't find anything like this.
For that matter, I was wondering if anyone had written a version of
`methods`
