I think this is bug in R CMD check code. I get a similar error:
rule: possible error in paste0(...): ... used in a situation where it
does not exist
for the simple:
rule <- function(..., pad = "-") {
if (nargs() == 0) {
title <- ""
} else {
title <- paste0(...)
}
width <- getOption("width") - nchar(title) - 1
message(title, " ", paste(rep(pad, width, collapse = "")))
}
where ... clearly does exist.
I skimmed the commits for the last couple of days - the most relevant
would seem to be this one by Michael Lawrence:
https://github.com/wch/r-source/commit/d3a42dabccb23462aa1e0a1edad00450f0a6131c
(but I might've missed others - many of the commit messages are not
terribly explanatory)
