[SPARK-10760] [SPARKR] SparkR glm: the documentation in examples - family argument is missing
Hi everyone,
Since the family argument is required for the glm function, the execution of:
model <- glm(Sepal_Length ~ Sepal_Width, df)
is failing.
I've fixed the documentation by adding the family argument and also added the summay(model) which will show the coefficients for the model.
Thanks,
Narine
