Re: coerce() methods.
Important to realize that as() does not call selectMethod() in the standard
way, but restricts inheritance to the first argument:
asMethod <- selectMethod("coerce", sig, optional = TRUE,
c(from = TRUE, to = FALSE), fdef = coerceFun,
A
Or maybe the "right" concept is that "numeric" is a virtual class
with 3 subclasses: "complex", "double", and "integer". Anyway it's
probably too late for implementing the "right" concept so it doesn't
really matter.
Thanks Martin for offering to fix the as(1L, "numeric") bug. Very
much
