Define function in scala using DataFrame type
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I would have a simple question...
I try to use a function that ate a datframe as argument and return another dataframe
I do:
val get_nb_previous_offre : ((DataFrame) => (DataFrame)) = (arg1: DataFrame) => {
// create new_df using arg1 (=DataFrame I pass in parameter)
new_df
}
I get the error:
<console>:32: error: not found: type DataFrame
val get_nb_previous_offre : ((DataFrame) => (DataFrame)) = (arg1: DataFrame) => {
Is there a librairy I have to import to use DataFrame as a type for my function?
