In nanny: High-Level Data Analysis and Manipulation in 'tidyverse' Style

Description

impute_missing() takes as imput a 'tbl' formatted as | <element> | <feature> | <value> | <...> | and returns a 'tbl' with an edditional adjusted value column. This method uses scaled counts if present.

Usage

## S4 method for signature 'tbl_df'
