[R] problem with all/all.equal

Hi!

In a function, I may have an instance in which all elements are equal.

> x <- rep(1,5)
>
> x
[1] 1 1 1 1 1
> identical(x)
Error in .Internal(identical(x, y, num.eq, single.NA, attrib.as.set)) :
  'y' is missing
> all.equal(x)
Error in is.expression(x) : 'x' is missing
>

I don't care what particular value it is, I just want to know if they are
all equal.

What am I doing wrong, please?

Thanks,
Laura
