recode_factor不能替换丢失的值

Question

我对recode_factor函数有个问题。出于某种原因，我不能用“失踪”代替NAs。

这是我的尝试

recode_factor(Data$i_ypsocweb, `1` = "yes", `2` = "no", missing = "missing")

值没有被替换，我看到了一个错误

由coercionUnreplaced值引入的NAs作为.x处理为NA是不兼容的。请指定替换或供应.default。

更糟糕的是，当我以轴方式打开数据集并找到值时，它没有被更改。我还是能得到数值

没有样本数据，但其中一个应该得到您所需要的。在下面的示例数据中，x是一个数值数组，而y是一个因素。

library(dplyr)

set.seed(1)
x <- sample(c(1, 2, NA), size = 15, replace = TRUE)
y <- as.factor(x)

x %>% recode(`1` = "yes", `2` = "no", .missing = "missing")
[1] "yes"     "missing" "yes"     "no"      "yes"     "missing" "missing" "no"      "no"      "missing" "missing"
[12] "yes"     "yes"     "yes"     "no"

case_when(y == 1 ~ "yes", y == 2 ~ "no", is.na(y) ~ "missing")
[1] "yes"     "missing" "yes"     "no"      "yes"     "missing" "missing" "no"      "no"      "missing" "missing"
[12] "yes"     "yes"     "yes"     "no"
