See these Rcpp Gallery article from 2012 for worked examples:
has an example on pnorm that applies to your dnorm case
discusses the RNGs, but the d/p/q functions behave the same way.
You can search at the Gallery too ...
So we have all the scalar functions in the R:: namespace, sugar ones in
Rcpp::, you can of course call the R functions as well (though I'd use R::(
plus you get access from Armadillo, Boost, GSL, ... via other packages.
But you need to look closely at the signatures of functions you are calling.
Those expecting a 'double' cannot magically be resolved with a
'Rcpp::NumericVector' as those are different types.
