replace_na_if(x, condition, true)

Arguments

x

Vector with missing values to modify.

condition

A logical vector

true

The replacement values where condition is TRUE.

Value

A modified version of x that replaces any missing values where condition is TRUE with true.

Details

replace_na_if() is a wrapper on if_else2(is.na(x) & condition, true, x)

Examples

data <- tibble::tibble(
  x = c(TRUE, FALSE, NA),
  y = c("x is false", NA, "x is false")
)

dplyr::mutate(data,
  x1 = tidyr::replace_na(x, FALSE),
  x3 = if_else2(is.na(x) & y == "x is false", FALSE, x),
  x4 = replace_na_if(x, y == "x is false", FALSE)
)
#> # A tibble: 3 × 5
#>   x     y          x1    x3    x4

#> 1 TRUE  x is false TRUE  TRUE  TRUE 
#> 2 FALSE NA         FALSE FALSE FALSE
