Struct DataFrameNaFunctions

pub struct DataFrameNaFunctions { /* private fields */ }

Functionality for statistic functions with DataFrame.

Implementations

impl DataFrameNaFunctions

pub fn drop( self, how: &str, threshold: Option<i32>, subset: Option<Vec<&str>>, ) -> DataFrame

Returns a new DataFrame omitting rows with null values.

pub fn fill<'a, I, T, L>(self, cols: Option<I>, values: T) -> DataFrame

where I: IntoIterator<Item = &'a str>, T: IntoIterator<Item = L>, L: Into<Literal>,

Replace null values, alias for df.na().fill().

pub fn replace<'a, I, T, L>( self, to_replace: T, value: T, subset: Option<I>, ) -> DataFrame

where I: IntoIterator<Item = &'a str>, T: IntoIterator<Item = L>, L: Into<Literal>,

Returns a new DataFrame replacing a value with another value.
