Title: Make unit tests a bit more faster

Change addPackage to use `plyr` instead of `Matrix` to reduce time taken to load the package. Also make the broadcast variables smaller.

Note that a more permanent fix is to use long running R daemons in the executors to avoid reloading packages for every closure.
