Under the hood, SparkR uses MLlib to train a model of the specified family. In Spark 1.5, we support a subset of the available R formula operators for model fitting, including '~', '.', '+', and '-'. The example below shows the use of R formulae with SparkR. --- End diff -- Actually it'll be better to talk about the families and link functions supported here before the formula. Also we could reword the example sentence to say `the example below shows the use of building a gaussian GLM model using SparkR`.
