I'll probably have to look in the R source code how dispatching of single indexes is done. Testing for missing(j)
does not tell me whether it's [i]
or [i,]
.

Found a (fairly obvious) solution: nargs
will be 2 if only i
is passed, and 3 if both i
and j
are passed.

That is right. I am not sure what they do. what about setting NULL as
default for both i and j and then checking is.null() instead of
is.missing()?

You're right, @gdlc, I just tried it and checking is.null()
would have worked, too. [
is a primitive method, and it seems like their dispatch is a lot more relaxed than say S4. I wanted to keep a simple signature, so missing()
and nargs()
are working pretty well.
