The below looks like the show method has trouble with the default call
object (or that there is no default call object). Not sure if this is a
bug, design problem, or a difficulty on my part using and extending the
call class, but it has caused difficulty for when I want to extend the
call class into other S4 classes.
> new("call")
Error in print("<undef>"()) : couldn't find function
"<undef>"
This error pops up when I show an object with an empty call slot.
Error in show("<undef>"()) : Unable to find the argument
"object" in
selecting a method for function "show"
I'll leave it up to the developers to designate this as a bug or not,
but I would certainly prefer that new() and show() never reports errors
when an empty object is passed as an argument (of any class).
Best,
Robert
