Add column to DataFrame in sparkR

Question

I would like to add a column filled with a character N in a DataFrame in SparkR. I would do it like that with non-SparkR code :

df$new_column &l         


        

Answer 1

The straight solution will be to use SparkR::lit() function:

df_new = withColumn(df, "new_column_name", lit("N"))

In newer Spark versions, the following also works:

df1$new_column <- "N"
df1[["new_column"]] <- "N"

Answer 2

There's an easier way to use SparkR::lit() that more closely mimics the syntax you tried first:

df$new_column <- lit("N")
