[R] matrix: suspected integer overflow

[andreas.krause@pharma.novartis.com]

Is the following a known issue, in particular in terms of message clarity of the latter two?

> matrix(0, 10^8, 10^8)
Error: cannot allocate vector of size 2064896 Kb
> matrix(0, 20, 10^10)
Error in matrix(0, 20, 10^10) : negative length vectors are not allowed
> matrix(0, 10^10, 10^10)
Error: cannot allocate vector of size 0 Kb

# looks better for arrays:

> array (0, c(20, 10^10))
Error: cannot allocate vector of size 4194303 Kb
In addition: Warning message:
inaccurate integer conversion in coercion
>
> array(0, c(10^10, 10^10))
