dropNaNs
The Drop NaN Operation
Removes rows with values. Specific case of NaNdrop.
Optionally, you can select which columns to operate on (see org.jetbrains.kotlinx.dataframe.api.DropNaNs.DropNaNsSelectingOptions). Also, you can supply whereAllNaN = true to only drop rows where all selected cells are . By default, rows are dropped if any of the selected cells are NaN.NaN
For more information: See dropNaNs on the documentation website.
See also fillNaNs, which replaces values instead of removing rows.NaN
This Drop 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.

See Column Selectors on the documentation website.
For example:
df.dropNaNs{ colsOf<Double>() }
df.dropNaNs(whereAllNaN = true) { colsOf<Double>() }
Parameters
The Columns Selector used to select the columns of this DataFrame to drop rows in.
