See also dropNaNs, which removes rows with NaN values instead of replacing these values.

The columns to update need to be selected. See Selecting Columns for all the selecting options.

This Fill NaNs Overload

Select or express columns using the Columns Selection DSL.

This DSL is initiated by a Columns Selector lambda, which operates in the context of the Columns Selection DSL and expects you to return a SingleColumn or ColumnSet (so, a ColumnsResolver). This is an entity formed by calling any (combination) of the functions in the DSL that is or can be resolved into one or more columns.

The Columns Selection DSL allows using Extension Properties for specifying columns type- and name-safe.

df.fillNaNs{ length andage }

df.fillNaNs{ cols(1..5) }

df.fillNaNs{ colsOf<Double>() }
