Hello,

I have 2 vectors of the same mode and the same contents but I still get FALSE. Any ideas ?

> reference <- c(11, 14, 16, 5, 4, 2,  0, 15, 9, 0)
> reference
 [1] 11 14 16  5  4  2  0 15  9  0
> cpgDensity
 [1] 11 14 16  5  4  2  0 15  9  0
> identical(cpgDensity, reference)
[1] FALSE
> mode(cpgDensity)
[1] "numeric"
> mode(reference)
[1] "numeric"
> cpgDensity == reference
 [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE

Thanyou,
         Dario.
