I get this hard-to-track error when I try to wrap a diffPrint (or any similar function) in another function and pass it dots:
library(diffobj)
fn <- function(target, current, ...) {
diffPrint(target, current, ...)
}
fn("a", "b", format = "raw")
#> Error in match.call(definition = get.fun, call = found.call) :
#> ... used in a situation where it does not exist
#> < NULL
#> > NULL
#> @@ 1 / 1 @@
#> < [1] "a"
#> > [1] "b"
The especially weird part is that while the error prints, it does not stop execution - I get the diff object back. And it is an error - it does not go away if I suppress messages or warnings.
