Shouldn’t you include the y argument also inmyscale.default ? Your generic is
defining that argument as well.
I assume (hopefully correctly) that methods don't need to include all the arguments of
the generic. I get the same warning if I use "..." instead of y, too.
No, your assumption is backwards. The methods do need to include all
arguments of the generic. As Writing R Extensions says near the start
of section 7, "A method must have all the arguments of the generic,
including … if the generic does."
Think about your user. They'll ask about help for `inmyscale`, and see
that it has two arguments, x and y. If x is a type that goes to
`inmyscale.default`, the user would receive an error when they followed
the docs and included the y value.
The usual way to handle this is to include both x and y in all methods,
but document some of them to say that y is ignored.
