 pkg list 

will give you the list of installed packages. If a package you need is 
not installed you can install it by

  pkg install -forge <package name>

even if a package is installed you need to load it before you can use it,

  pkg load <package name>

will load a package, once it is loaded, if you look at the list again it will 
be 
marked as an "*" . 

look at the manual [1] or the wiki [2,3] for more info.
