Hi all,
How can I call the default method of a S3 object defined by a
primitive method? i.e. in the following example, how do I call the
default [ method instead of the one I defined for the class.
new_a <- function(x) structure(x, class = "a")
a <- new_a(1:5)
"[.a" <- function(x, i, j, ...) {
new_a(x[, j, ])
What about
new_a(unclass(x)[, j,])
Cheers,
Simon
}
a[, 5]
Thanks,
Hadley
