Dear Developers,
callNextMethods does not work with "$"
setClass("mylist", contains = "list"):
setMethod("$",
signature(x = "mylist"),
function (x, name){
cat("here:\n")
callNextMethod()
})
tl <- new("mylist")
tl[["x"]] <- 343
tl$x
#here:
#NULL
If I use callNextMethod(x=x, name=name)
this error is issued:
Error in function (classes, fdef, mtable) :
unable to find an inherited method for function "addNextMethod", for
signature "function"
It must be something "$" specific. If the above is an expected behavior , how
should I call next method for "$" generic?
My info:
R version 2.12.0 Patched (2010-11-01 r53513)
Platform: i386-pc-mingw32/i386 (32-bit)
Same behavior for official R 2.12.0.
Thanks,
Vitalie.
