cast_shadow {naniar}

Add a shadow column to a dataset

Description

Casting a shadow shifted column performs the equivalent pattern to data %>% select(var) %>% impute_below(). This is a convenience function that makes it easy to perform certain visualisations, in line with the principle that the user should have a way to flexibly return data formats containing information about the missing data. It forms the base building block for the functions cast_shadow_shift, and cast_shadow_shift_label. It also respects the dplyr verbs starts_with, contains, ends_with, etc. to select variables.

Usage

cast_shadow(data, ...)

Arguments

data

data.frame

...

One or more unquoted variable names separated by commas. These respect the dplyr verbs starts_with, contains, ends_with, etc.

Value

data with the added variable shifted and the suffix ⁠_NA⁠
