R-alpha: inheritance ([.ts)
Thu, 11 Dec 1997 13:46:44 -0500
While commenting out the previously mentioned warning seems to work, I have been
reflecting on this problem and there seems to be an issue wrt inheritance that I
do not understand properly. Perhaps some gurus could comment.
As mentioned previously, I have a class "tframe" with more specific classes
indicating how time is being represented, such as
 "ts" "tframe"
and in R0.60 "[.ts" produces warning messages when I use tframe(data).
Now tframe(data) is NOT a "ts", it is a specific kind of "tframe". When I coded
this I was expecting it would use "[.default", so to date I guess it has just
been working accidentally.
Does the fact that there is a class "ts" mean that one should not have another
class with "ts" as its more specific class? This seems like a pretty severe
