Hi, I just tried to calculate the density of a normal variable using dnorm.
I found that if the input is of type NumericVector, then it was fine. But
if the input is of type double, it yielded error in compilation. For
example:
// [[Rcpp::export]]
NumericVector test5(NumericVector x)
{
NumericVector y = dnorm(x,5.0,2.0,true);
return(y);
}
and
// [[Rcpp::export]]
double test6(double x)
{
double y = dnorm(x,5.0,2.0,true);
return(y);
}
May I ask why and how can I calculate this density (and call other common
functions like dbeta, dt, beta, gamma, lbeta, lgamma, etc...) on double
input?
Many thanks,
Eridk
