Hi again,
Here is a very simplified version of a class hierarchy
defined in the Biobase package (Bioconductor). I post
here because this seems to be an S4 related problem:
setClass("A", representation(name="character"))
setMethod("initialize", "A", function(.Object) [EMAIL PROTECTED] <- "I'm
an A"; .Object})
setClass("Ab", contains="A")
setMethod("initialize", "Ab", function(.Object) callNextMethod(.Object))
setClass("Abc", contains="Ab")
setClass("Abcd", contains = c("Abc"))
Now if I do:
tmp1 <- new("Abc")
tmp2 <- new("Abcd")
I get the following warning:
Warning message:
Ambiguous method selection for "initialize", target "Abcd" (the
first of the signatures shown will be used)
Abc
Ab
in: .findInheritedMethods(classes, fdef, mtable)
I don't really understand why .findInheritedMethods is
complaining here...
And if I don't do 'tmp1 <- new("Abc")' before I
do 'tmp2 <- new("Abcd")', then I don't get the warning
anymore!
Does anybody have an explanation for this?
Thanks,
H.
