Description

SparkR subset function throw error when only set "select" argument, it's easy to repreduce.
In SparkR:

> df <- suppressWarnings(createDataFrame(sqlContext, iris))
> subset(df, select=c("Sepal_Length", "Petal_Length", "Species"))
Error in x[subset, select, ...] : 
  error in evaluating the argument 'i' in selecting a method for function '[': Error: argument "subset" is missing, with no default

But in base R, the subset function works well with only specifying "select" argument:

> df <- iris
> subset(df, select=c("Sepal.Length", "Petal.Length", "Species"))
    Sepal.Length Petal.Length    Species
1            5.1          1.4     setosa
2            4.9          1.4     setosa
3            4.7          1.3     setosa
4            4.6          1.5     setosa
5            5.0          1.4     setosa
