fct_explicit_na: Make missing values explicit

Description

This gives missing values an explicit factor level, ensuring that they appear in summaries and on plots.

Usage

fct_explicit_na(f, na_level = "(Missing)")

Arguments

f

A factor (or character vector).

na_level

Level to use for missing values: this is what NAs will be changed to.

Examples

f1 <- factor(c("a", "a", NA, NA, "a", "b", NA, "c", "a", "c", "b"))
fct_count(f1)
table(is.na(f1))

f2 <- fct_explicit_na(f1)
fct_count(f2)
table(is.na(f2))
