I am trying to extend the class "call", but keep getting errors whatever I do:
setClass("mycall", contains = "call")
#Error in function (object) :
# error in evaluating the argument 'object' in selecting a method for function
#Error in .getClassFromCache(Class, where) :
# could not find function "<undef>"
I understand this is rarely needed, but for some special reasons I really need
the class "call" (as usually returned by quote and substitute) and not class
Would really appreciate any workarounds.
