如何根据 R 中另一个变量的值更改变量中的值？

Question

我正在尝试重新编码人口统计变量。如果变量Q36等于Other，变量Q35等于Yes，我想把Other（从Q36）改成Hispanic。如果变量Q36等于Other，变量Q35等于No，我想把Other（从Q36）改成Unspecified.

到目前为止，这是我的代码。

data %>% 
  mutate(Q36 = case_when(Q35 == "Yes" & Q36 == "Other" ~ Q36 == "Hispanic", 
Q35 == "No" & Q36 == "Other" ~ Q36 == "Unspecified")) -> data

你很接近：

data %>% 
  mutate(Q36 = case_when(Q35 == "Yes" & Q36 == "Other" ~ "Hispanic", 
                 Q35 == "No" & Q36 == "Other" ~ "Unspecified",
                TRUE~Q36))

如何根据 R 中另一个变量的值更改变量中的值？
