impute_functions: Table imputation methods

Description

Replace missing value methods with a variety of methods

Usage

impute_functions(.tbl, .na, .vars, .predicate)

Arguments

.tbl

table-like or list-like structure

.na

value/function to be used for replacement

.vars

list of columns generated by vars(), or a character vector of column names, or a numeric vector of column positions.

.predicate

A predicate function to be applied to the columns or a logical vector.

...

addition passed to the imputation method

Details

These methods are modelled closely after dplyr::mutate() and the select style verbs. Most of the functions depend on the na.tools package.
