Calling `list(...)` will return a list as long as there are elements
caught in `...`
Does this help?
R> howMany <- function(...) {
args <- list(...)
cat("There are", length(args), "items passed in here\n")
}
R> howMany(1, 2, 3, 4)
There are 4 items passed in here
R> howMany(10, list(1:10))
There are 2 items passed in here
