My question is very obvious: Is there any package to handle missing values in R?
I think this task can be done almost in an automatic way. I mean, we can have a function like the one below which is simply a quick pseudo function:
handle_missing_values( dataframe, threshold_remove_variable: 40% # remove the variable when the missing value amount is greater or equal than 40% default_imputation_numeric_variables: "mean", default_imputation_categoric_variables: "Not Specified", imputation_numeric_variables: c( field5: "knn", field8: "prediction" ), imputation_categoric_variables: c( field2: "Not Asked" ), remove_rows_with_missing_values_at_the_end: true )
Thanks in advance!
