Why it is happeing?

[Bogaso]

Dear all, I had following calculations with R:
> x = vector(length = 4)
> x[1] = 1
> x[2] = 3
> x[3] = 123456789123456
> x[4] = -9876543219876
> as.integer(x)
[1]  1  3 NA NA
Warning message:
NAs introduced by coercion

What went wrong?

Thanks and regards,

"Note that current implementations of*R*use 32-bit integers for integer
vectors, so the range of representable integers is restricted to
about/+/-2*10^9/:|double
<http://stat.ethz.ch/R-manual/R-patched/library/base/html/double.html>|s
can hold much larger integers exactly."
