How to call a package

[AlfonsoRReyes]

Hello:
I am trying to call the statistics package from RcppOctave like this:

.CallOctave("pkg load statistics")

But I get this error:
Error in .CallOctave("pkg load statistics") :
RcppOctave - error in Octave function pkg load statistics:
feval: function 'pkg load statistics' not found

My Linux Octave (Mint 18) can load the package with no problem.
