Variable handling functions#
Feature-engine functions for finding variables of a specific type or ensuring that the variables are of the correct type.
The functions take a dataframe as an argument and return the names of the variables in the desired type.
You can also pass a dataframe with a list of variables to check if they are all of the desired type.
These functions are used under the hood by all Feature-engine transformers to select the variables that they will modify or operate with.
