recode_if(cond, yes, no)

Arguments

cond	condition
yes	value when condition is true
no	value when condition is false **or NA**

Examples

x <- c(rnorm(100), NA_real_)
y <- c(rnorm(100), NA_real_)
bench::mark(
    dplyr::case_when(x < 0 ~ 10, T ~ x),
    recode_if(x < 0, 10, x),
    relative = T
)
bench::mark(
    dplyr::case_when(x < 0 ~ y, T ~ x),
    recode_if(x < 0, y, x), 
    relative = T
