Yanbo Liang updated SPARK-12234:
--------------------------------
Description:
SparkR subset throw error when only set "select" argument, it's easy to
repreduce.
In SparkR:
{code}
> 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
{code}
But in base R, the subset function works well with only specifying "select"
argument:
{code}
> 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
......
{code}
