当计算class = case_in R时，问题怎么解决呢？

下面是我的数据集的dput(head(temp))：
第一个
这就是我想通过的：

temp <- temp %>% mutate(class = dplyr::case_when(gini.total >= 0.5 & gini.dom >= 0.5 & species == "single" ~ "single species irregular",
                                    gini.total >= 0.5 & gini.dom < 0.5 & species == "single" ~ "single species admixture",
                                    gini.total >= 0.5 & gini.dom >= 0.5 & species == "multiple" ~ "multiple species irregular",
                                    gini.total >= 0.5 & gini.dom < 0.5 & species == "multiple" ~ "multiple species layered",
                                    gini.total < 0.5  & species == "single" ~ "single species regular",
                                    gini.total < 0.5  & species == "multiple" ~ "multiple species regular", TRUE ~ NA_real_))

而我只是得到这个错误，它没有解释它发生的位置和原因：

Error in `mutate()`:
! Problem while computing `class = dplyr::case_when(...)`.
Caused by error in `dplyr::case_when

有人知道我做错了什么吗？

尝试将NA_real_更改为NA_character_。错误消息应该是这样的：“无法在该列中混合真实的和CHARACTER。”
