Hi all,
My package defines the following method and generic:
chop <- function (x, ...) UseMethod("chop")
chop.default <- function (x, breaks, labels, extend = NULL, drop = TRUE) {
... }
R CMD check then gives a warning:
W checking S3 generic/method consistency (695ms)
chop:
function(x, ...)
chop.default:
function(x, breaks, labels, extend, drop)
See section ‘Generic functions and methods’ in the ‘Writing R
Extensions’ manual.
I can fix this by adding a ... argument to chop.default:
chop.default <- function (x, breaks, labels, extend = NULL, drop =
TRUE, ...)
But that makes the code less robust because e.g.
chop(x, Breaks = 1:3)
will no longer throw an error from the misspelled argument.
Or I can write:
chop(x, breaks, labels, extend, drop) UseMethod("chop")
but this means I cannot use a different interface for a different method.
This seems like a mistake. (That's the polemic.) Or am I missing a better
way? (That's the question.)
