#***Note, be sure to load in a library if you're calling something outside of native R for this function***

#Some possible ways to use this function:
glm_args = GetArgs(h2o.glm)
dl_args = GetArgs(h2o.deeplearning)
gbm_args = GetArgs(h2o.gbm)
rf_args = GetArgs(h2o.randomForest)
kmeans_args = GetArgs(h2o.kmeans)
