我有一个SparkR DataFrame，我想（最常见）value获取每个唯一模式name。我怎样才能做到这一点？似乎没有内置mode功能。SparkR或PySpark解决方案都可以。

#Create DF
df <- data.frame(name = c("Thomas", "Thomas", "Thomas", "Bill", "Bill", "Bill"),
  value = c(5, 5, 4, 3, 3, 7))
DF <- createDataFrame(df)

name   | value
-----------------
Thomas |  5
Thomas |  5
Thomas |  4
Bill   |  3
Bill   |  3
Bill   |  9

#What I want to get
name   | mode(value)
-----------------
Thomas |   5
Bill   |   3
