trouble with S4 methods for group "Summary"
Hello. This question concerns the Methods package. I have created a
new class and am trying to set a method for it for S4 group generic
"Summary". I have run into some signature problems. An example:
> setClass("track", representation(x="numeric", y="character"))
[1] "track"
> setGeneric("max", group="Summary")
