基于多个条件创建因子变量的R-Tidy方法

我有这样一个数据集：

Gender<-c("Male","Female","Male","Male","Female")
PlaceA<-c("","","","1600","")
PlaceB<-c("","200","211","326","")
PlaceC<-c("1111","2222","","","45")
PlaceD<-c("1000","","","1600","210")
DF<-tibble(Gender,PlaceA,PlaceB,PlaceC,PlaceD)

时使用
case\u
？正如@IceCreamToucan所提到的，
case\u当
时应该在这里起作用，只是要小心从最具体到最一般的条件开始列出-请参见此处的“模糊嗡嗡声”示例：您是否尝试过在
