How does one invoke class methods via XPtr objects in R? I get this error:
Error in aptr$f : object of type 'externalptr' is not subsettable:
cpp file:
#include
struct A {
void f() {}
};
typedef Rcpp::XPtr APtr;
APtr getAPtr()
{
return APtr(new A);
}
struct B {
B(APtr) { }
};

I don't understand what you are trying to do below, and do not have time to

All I want to do is obtain a shared-pointer equivalent in R to a C++ object and
be able to do two things with it - 1. Invoke methods of the object via the
shared-pointer and 2. pass the shared-pointer to the methods of other C++ class
objects.
In Python, I am able to do this like so (Boost shar

double qpd = R::qnorm(pd, 0, 1, 1, 0);

double sg = 0.3;
double eor = 1;
double w = 0;
while (eor>=0.0001) {

I am fairly certain that this line is not kosher (and in any case it is a
confusing):
w = pd * 0.4 / (R::pnorm((qpd - sqrt(rsq) * (-0.42) * sgtemp), 0, 1, 1,
0));
try this instead:
w = qpd - sqrt(rsq) * (-0.42) * sgtemp
w = pd * 0.4 / (R::pnorm(w, 0, 1, 1, 0));
