impute_below_at: Scoped variants of impute_below

Description

impute_below operates on all variables. To only impute variables that satisfy a specific condition, use the scoped variants, impute_below_at, and impute_below_if. To use _at effectively, you must know that _at`` affects variables selected with a character vector, or with vars()`.

Usage

impute_below_at(.tbl, .vars, prop_below = 0.1, jitter = 0.05, ...)

Value

an dataset with values imputed

Arguments

.tbl

a data.frame

.vars

Examples

# select variables starting with a particular string.
impute_below_at(airquality,
                .vars = c("Ozone", "Solar.R"))

impute_below_at(airquality, .vars = 1:2)

if (FALSE) {
library(dplyr)
impute_below_at(airquality,
                .vars = vars(Ozone))

library(ggplot2)
airquality %>%
  bind_shadow() %>%
  impute_below_at(vars(Ozone, Solar.R)) %>%
  add_label_shadow() %>%
  ggplot(aes(x = Ozone,
             y = Solar.R,
             colour = any_missing)) +
         geom_point()
