How to call a package

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.
