Having looked at the code, there is little reason to use plyr in neotoma. Removing a dependency should make maintaining the package into the future that bit simpler.
I have a branch in my repo that has completely removed the dependency on plyr. It is ready to be pulled once #29 is merged, should you wish to merge it. At the moment if I do a pull request on that branch, it will try to merge #29 and the new changes in my noplyr branch.
