[R] odd error with rJava

[Joshua Wiley]

Hi Erin,

You need to make sure that rJava both installs correctly and can load.
 The R package system is quite robust, so off the top of my head, I
would guess you need to setup Java properly on the machine.  See the
rJava package for what it requires.

Cheers,

Josh
