One way is to look at .Machine$sizeof.pointer -- 4 on 32-bit and 8 on 64-bit.

.Machine$sizeof.pointer is 4 or 8.

Hello,
Is there a way to query whether R has been compiled using 32- or
64-bits? A certain memory-intensive simulation will need to be optimized
differently depending on the memory constraints of the architecture such
that it will run quickly in 64-bits, and will run within ~3GB under
32-bits. And

I like this idea.

This is indeed in the manual you mention. To use R functions and not just
standalone libRmath, you need to embed R.

Hi,
I have a question for building a standalone exe file via C/C++ with R and
add-on packages in Windows (Compiler is VC). It may looks like ...
#include
#include
int main() {
double *x, *y, z;
// ... (Variables initial)
z = ar( x, ...);
// In this example, I want use the ar (tim

Hi,
iff is shorthand typically used in mathematical proofs. You have
probably found the one group (users of R) that have the highest
probability of knowing the meaning of "iff". That said, I agree that
it should not be used in official documentation. It should be
replaced with "if and o

Please do note that this too is a reading error. The documentation for
rowsum() says
group: a vector giving the grouping, with one element per row of
'x'.
R has used 'group' as if it were as.vector(group), as it was entitled to
do. If you do not want that, give a _vector_ with th
