Why should you do that? In other words: Why change the argument list of your function(s) ? That \Sexpr{} does not work as a section is "obvious" (for some), but I really don't see why you should change the argument list or defaults of your hdara package functions at all.

Re: [Rd] Compatibility issues caused by new simplify argument in apply function
I am sorry for being not specific enough. Both of you were right with your guess how the initial problem looked like. I followed the suggestion of Henrik and at least on my computer it seems to work (sometimes solutions are much easier than you think). Let's see what CRAN tells me...

I'm very rusty on S4 but would one solution be to, already now, add 'simplify = TRUE' to the S4 method and document it; setMethod("apply", signature(X = "Speclib"), function(X, FUN, bySI = NULL, ..., simplify = TRUE) { ? Yes, that sounds like an ideal solution. The docs can say it is ignored in old versions and passed on in new ones.

Certainly you can have conditional code, but the docs are going to fail. One thing that might work is in versions of R before this change, export your own version of apply, with the change in place, i.e. if(!("simplify" %in% names(formals(base::apply apply <- function(X, MARGIN, FUN, ..., simplify = TRUE) { base::apply(X, MARGIN, FUN, ...) } and then conditionally export "apply" in these old versions. Then your docs could match the new version everywhere. Another thing is to maintain two versions of your package, one for R versions before the change, another for versions after the change. Add appropriate entries in the DESCRIPTION file, e.g. Depends: R (> 4.0) Another is to argue with R Core that this change to a really old function is too hard to accommodate, and they should back it out, maybe by making a new function with the new signature. Or you could make a new function with the old signature, and use that instead of apply().

You didn't explained what the error is. This is what it looks like to me, but I'm probably wrong in some details: 1.
