The unit tests are indeed very helpful.  However, I have been trying to
figure out how the unit tests were developed.  As far as I can see,
there is nothing in Rcpp nor Rmath.h that actually specifies the
prototypes like the example above (and I did look, hence my initial
confusion about the syntax of qnorm).  Were these written simply by
looking at the R help itself like ?qnorm or were they automated in
some way?  Thanks
