Subject: [R] nargs() inside "[.myclass"

I am writing a function to work with class I am defining. I have a question
about using nargs() inside of parentheses function. nargs() shows the same
for supplying 1 argument, or no arguments at all. Here is a small example:

> "[.myclass"<-function(x,...) print(nargs()-1)
> x<-c(1,2,3)
> class(x)<-"myclass"
> x[]
[1] 1
> x[1]
[1] 1
> x[1,2]
[1] 2

how can I determine if there was 1 argument supplied, or none?

Thanks.
