Shivaram Venkataraman commented on SPARK-9230: ---------------------------------------------- [~ekhliang] [~mengxr] One more thing that would be good to do is to make these formulas also work with actual columns in R. For example in DataFrames we parse columns with df$col_name. So it will be great to support a formula of the kind df$Sepal_Length ~ df$Sepal_Width > SparkR RFormula should support StringType features > -------------------------------------------------- > > Key: SPARK-9230 > URL: https://issues.apache.org/jira/browse/SPARK-9230 > Project: Spark > Issue Type: New Feature > Components: ML, SparkR > Reporter: Eric Liang > > StringType features will need to be encoded using OneHotEncoder to be used > for regression.
