R 如果单元格为空，则更改数据帧,r,R,我有一个如下所示的数据框架，我想动态地为我的脚本提供DEPT\u Head=“DEV0001” df <- data.frame(HOD_ID =c("","KTN2252","ANA2719","ITI2624","DEV2698","HRT2921","","KTN2624","ANA2548","

我有一个如下所示的数据框架，我想动态地为我的脚本提供
DEPT\u Head=“DEV0001”

df <- data.frame(HOD_ID =c("","KTN2252","ANA2719","ITI2624","DEV2698","HRT2921","","KTN2624","ANA2548","ITI2535","DEV2732","HRT2837","ERV2951","KTN2542","ANA2813","ITI2210"),
                 DEPT_Head = c("DEV0001","KTN2252","ANA2719","ITI2624","DEV2698","HRT2921","ERV0000","KTN2624","ANA2548","ITI2535","DEV2732","HRT2837","ERV2951","KTN2542","ANA2813","ITI2210"))


df您可以尝试：


DEPT_Head = "DEV0001"
df$if_blank <- as.integer(df$DEPT_Head != DEPT_Head & df$HOD_ID == '')



DEPT\u Head=“DEV0001”

df$if_blank这行吗？df%>%mutate（如果\u blank=case\u时（HOD\u ID=''和DEPT\u Head！=“DEV0001”~1，TRUE~0））是的，这对我不起作用这就是为什么我在寻找解决方案如果
提供的
DEPT\u Head
的
HOD\u ID
不是空的，你想做什么？它可以是空的，所以对于没有突变的列，只有0，在此之后，所有空单元格为1
