R as 64 bit application

In a package test I have a problem that needs over 4G of memory. This requires that I use R compiled as a 64 bit application. Is there a way within R to test if R has been compile as a 64 bit application? This would allow me to automatically skip the test when I know it is going to fail.
I don't think so. You could use a simple C function
void is64bit (int *sizeptr){
*sizeptr = sizeof sizeptr ==8;
return;
}
is64bit<-function(){
.C("is64bit",logical(1))[[1]]
}
