Hi Devesh,
RFormula will encode category variables(column of string type) as dummy
variables automatically. You do not need to do dummy transform explicitly
if you want to train machine learning model using SparkR. Although SparkR
only supports a limited ML algorithms(GLM) currently.
Thanks

Yes, you can use Rformula library. Please see

Hi,
Can we create dummy variables for categorical variables in sparkR like we
do using "dummies" package in R
